The Residency Mindset: Principles for Becoming a Great Surgical Resident

Chris Hornung, MD ·

Originally published on Medium. Read the original article.

First, a caveat. I do not admit to being a great surgical resident. I do, however, aspire to be one. When I started residency, I thought becoming a better resident was mostly a matter of accumulating knowledge and technical skill. Read more. Operate more. See more patients. Those things are obviously important, but over the last two years I’ve become convinced they aren’t what separates residents who improve the fastest from those who don’t.

Two residents can read the same textbook, assist on the same operation, and receive the same feedback. Five years later, one has developed excellent clinical judgment while the other has simply accumulated experience. That difference has become increasingly interesting to me.

I think residency is fundamentally a five-year exercise in learning how to think. Every consult, every operation, every complication, every mistake, and every piece of criticism provides information about your current level of performance. The question isn’t whether those experiences happen — they happen to everyone. The question is whether you recognize them as opportunities to improve.

The framework below isn’t intended to be a list of motivational quotes or generic residency advice. It’s the collection of principles that have most influenced how I approach residency and how I’ve tried to learn from it based on the residents I have worked with that I think are truly great. The great residents I’ve worked with didn’t simply accumulate more experience. They were more deliberate about what they did with it.

Everything Is Feedback

When people think about feedback, they usually think about formal evaluations. Your program director meets with you a couple of times each year. You have mentor meetings. At the end of a rotation you receive written evaluations. That may amount to 10 or so definitive feedback sessions and subsequently many residents complain that they don’t receive enough feedback during their training. In my view, those conversations matter, but they represent only a small percentage of the feedback you receive during residency, and they are arguably the less important feedback modality.

Most feedback is informal.

What makes an attending take over part of an operation? What questions does your senior ask during a consult that you didn’t think to ask? What portions of your note consistently get rewritten? What tasks are you increasingly trusted to perform independently? Those moments happen every day, and they’re often far more informative than a formal evaluation because they occur in real time.

One of the biggest shifts in my mindset was learning to treat correction as data rather than criticism. If the same issue continues to come up, that isn’t evidence that I’m failing. It’s evidence that I’ve identified the next thing I need to improve.

Criticism Is Not Condemnation

Nearly everyone who enters residency has spent most of their academic career succeeding. You performed well enough to get into medical school, graduate, and match into your specialty. If you matched into a surgical residency then you were also almost certainly towards the top of the heap of your medical school class. Most of us are accustomed to being competent.

Residency changes that almost immediately.

For the first time you’re expected to make decisions in situations where you have very little experience. You will miss things. You’ll struggle in the operating room. You’ll make inefficient decisions. You’ll forget important questions. You’ll discover knowledge gaps that you didn’t realize existed.

Because of that, criticism can feel much more personal than it actually is.

I’ve found it helpful to separate my identity from my performance. Being told that I should have managed a consult differently isn’t the same thing as being told that I’m a bad resident. One is feedback about a specific performance. The other is a judgment about who I am. Residency provides the former constantly. It almost never provides the latter.

The sooner criticism stops feeling like condemnation, the easier it becomes to seek it out instead of avoiding it. Residency is the time you want to figure out what you are doing sub optimally so you can address it before you are practicing independently.

Grit

It’s 4:30 in the afternoon and you’re carrying the consult pager. Your shift is supposed to end at 5:00. Four new consults come in within the last thirty minutes of your shift.

The first patient needs a flexible laryngoscopy, but none of the scopes you pick up work. You eventually find one and finish the consult. The next patient needs a bedside biopsy. You evaluate them, gather your supplies, and walk back to the room only to realize you forgot something you need. You walk back across the hospital to get it.

It’s now 5:30. You still haven’t seen two of the consults. You’re hungry. You were supposed to leave a half hour ago. Your spouse is texting to ask when you’ll be home.

None of this is catastrophic. Nobody is coding. You didn’t make a major medical error. It’s simply one of those days when every small thing seems to take longer than it should.

This is the part of residency where grit matters.

Grit isn’t pretending that you’re happy to be there. It isn’t convincing yourself that residency isn’t difficult, and it isn’t tolerating poor working conditions without complaint. It’s what happens after you become frustrated.

Do you start rushing through the next consult because you want to go home? Do you stop reading about the patient because you’re tired? Do you become resentful every time the pager goes off? Do you avoid the operation you’re struggling with because it’s uncomfortable to repeatedly be bad at something?

Or do you continue to engage?

The residents who improve the most aren’t necessarily the ones who struggle the least. They’re the ones who remain engaged when training becomes frustrating, uncomfortable, or discouraging. They continue asking questions. They continue seeking opportunities to improve. They continue doing the next right thing even when the day isn’t going their way.

Own Your Education

One of the biggest differences between medical school and residency is that nobody is responsible for making sure you’ve learned something.

Your attendings provide opportunities. Your senior residents provide guidance. Your patients provide experience. None of them are responsible for turning those experiences into an education. If you rely on others to teach you everything you need to learn during residency, you will not be competent by the time you complete your training.

That responsibility belongs to you.

If you encounter a disease you’ve never heard of, look it up before the day ends. If an attending recommends a treatment you don’t understand, keep asking why until you do. Read about your patients. Identify your own weaknesses instead of waiting for someone else to identify them for you.

Your program is responsible for providing opportunities to learn. You are responsible for taking advantage of those opportunities.

Practice Thinking

One of the habits that has helped me the most is forcing myself to commit to an answer before someone else gives me theirs.

Read the CT before looking at the radiologist’s interpretation. Stage the cancer before discussing it with your attending. Develop a differential diagnosis before hearing your senior’s assessment. Decide what operation you would perform before asking what someone else plans to do.

You’ll often be wrong.

That’s exactly why it’s valuable.

Clinical judgment doesn’t develop by watching experienced physicians think. It develops by comparing your own reasoning with theirs and understanding where the two differ. Every incorrect assessment becomes an opportunity to recalibrate your thinking.

Commit to a decision and compare it to someone’s decision who has more experience than you. Calibrate how to make a better decision when a similar situation happens again. If you do that over and over throughout the course of your training, you will grow immensely.

The goal isn’t to be right every time. The goal is to make sure you’re actually thinking.

Reflection Is How Experience Becomes Judgment

People often say that experience is the best teacher. I don’t think that’s entirely true.

If it were, every graduating chief resident would be equally competent simply because they’d all seen thousands of patients and participated in hundreds of operations. We know that isn’t the case. Two residents can have nearly identical experiences and become very different surgeons.

Experience is the raw material. Reflection is what turns experience into judgment.

For me, reflection isn’t simply thinking about whether a case went well or poorly. It’s a structured process of comparing my thought process with reality. Every interesting consult, operation, or piece of feedback becomes an opportunity to recalibrate how I think.

I love to track things, ex1, ex2, ex3; so naturally, I had to mechanize tracking my feedback too. I keep a notes app on my phone that I update when I get that aforementioned informal feedback. I spammed ChatGPT to come up with a list of competencies within ENT spanning from interpersonal, clinical, and operative growth. You can find the template I use here.

Here is an example of a recent entry:

Full thickness skin graft

  • Developing; 7/7/26; left fat on the FTSG while taking it from the leg with scalpel. Graft will not take if there is fat because of imbibition, inosculation, neovascularization; Get in the correct plane right away so you don’t have to get the fat off with scissors at the end.

This process has changed the way I think about residency. I no longer see difficult consults, complications, or criticism as isolated events. They’re data points. Every one of them helps me recalibrate my judgment. Over time, those small calibrations compound. I think that’s one of the biggest differences between residents who merely accumulate experience and those who consistently improve from it.

Chase Uncertainty

If I hear a term I don’t recognize, I write it down and look it up before the day’s end. If I don’t understand why a treatment was chosen, I keep asking questions until I do. If I can’t explain a concept to an intern concisely in a way they can understand, I assume I don’t understand it well enough.

Recently, I was putting together a presentation on superior semicircular canal dehiscence. As I worked through the physiology, I found myself talking about things like perilymph, endolymph, and how pressure and fluid movement through the inner ear ultimately produce the symptoms of a third-window disorder. I knew enough to explain the disease, but I realized there was a layer underneath it that I didn’t understand as well as I wanted to.

So I stopped working on the presentation.

I went back to the basic anatomy of the cochlea and vestibular system. That led me into the membranous and bony labyrinths, the composition and compartments of perilymph and endolymph, and eventually deeper into cochlear microanatomy and the organ of Corti. What was supposed to be time spent building slides became time spent relearning the machinery that made the slides make sense.

I didn’t get very far on the presentation that day. But when I returned to SSCD, I understood it differently. I wasn’t just memorizing that a third window changes inner-ear mechanics. I had a better mental model of the system whose mechanics were being changed.

That is what curiosity looks like to me in practice. It is less a personality trait than a habit: noticing when your understanding rests on something you don’t actually understand, and being willing to follow that gap downward until you reach solid ground.

It can feel inefficient in the moment. Residency rarely rewards spending three hours learning something you could have memorized in ten minutes. But those detours accumulate. The next concept has somewhere to attach, and eventually you spend less time memorizing isolated facts because more of them become consequences of things you already understand.

Don’t assume you know. Know that you know.

Try to Prove Yourself Wrong

One of the easiest mistakes to make in medicine is becoming attached to your first impression.

Rather than asking myself what diagnosis best fits the presentation, I try to ask what diagnosis I would regret missing. Before an operation, I ask what intraoperative finding would completely change my management. During a consult, I ask what dangerous diagnosis needs to be excluded before I become comfortable with my assessment.

Medicine isn’t simply about finding evidence that supports your conclusion. It’s about actively looking for evidence that your conclusion is wrong.

Think in First Principles

Medicine comes with loads of memorization. It is just the nature of the beast. While memorizing facts may get you a few extra questions correct on your exams, they have diminishing returns when applied to clinical thinking. Failure to see the forest through the trees leads to knowledge that is not actionable. You can memorize that oral cancer leads to neck levels I-III neck dissections and that oropharyngeal cancer generally leads to II-IV, but the key is why? Why did those surgical principles develop? What is the actual role of a neck dissection in a patient with head and neck cancer?

The problem with memorization is that it doesn’t generalize.

Whenever possible, I try to understand the underlying principle instead of simply memorizing the answer.

  • Why does this operation work?
  • What problem is this maneuver trying to solve?
  • What anatomy dictates this approach?
  • What assumptions is this treatment based on?

Once you understand the mechanism, individual facts become much easier to remember because they’re connected to a larger framework.

Medicine becomes much less about memorization and much more about solving problems.

Buy Into Your Role

Every stage of residency has a different job. One of the easiest mistakes to make is becoming so focused on the next stage of training that you fail to master the one you’re currently in.

Interns often wish they were operating more. Junior residents want more autonomy. Senior residents want more complex cases. Those ambitions are healthy, but they can also distract you from what you’re actually supposed to be learning.

Early in residency, it’s easy to view floor work, consults, clinic, and documentation as obstacles that keep you out of the operating room. I think that’s the wrong way to look at it.

Those experiences aren’t interruptions to your surgical education. They are your surgical education.

The intern who learns to recognize a sick patient, efficiently work up a consult, communicate with consultants, prioritize competing tasks, and understand the natural history of disease is building the foundation that every good senior resident depends on. Likewise, the junior resident who learns to independently manage patients and make thoughtful clinical decisions is preparing to become the senior resident who can safely supervise others. Every stage builds the skills required for the next.

The operating room is only one component of becoming a surgeon. Judgment, communication, efficiency, leadership, and patient management are just as important. Those skills are developed long before you’re performing the most technically demanding portions of an operation.

I’ve found it helpful to ask myself a simple question:

“What am I supposed to be learning from the role I’m in today?”

That question changes how you view your responsibilities. Instead of seeing floor work as something to “get through,” you begin to recognize it as deliberate training for the physician you’re trying to become.

Don’t rush through one stage of residency just because you’re excited for the next. If you fully embrace the responsibilities of your current role, you’ll be far better prepared when the next opportunity arrives.

Become the Resident People Want Around

Knowledge and technical skill matter, but they aren’t the only reasons people enjoy working with someone. Every residency program has residents who are technically gifted but difficult to work with, and residents who everyone hopes are on call because they consistently make the service run more smoothly.

The difference usually isn’t intelligence. It’s awareness.

The residents who become trusted the fastest are the ones who continuously ask themselves, “What can I do right now that will make someone else’s job easier?”

Sometimes that’s following up on a pending consult before your senior has to remember it. Sometimes it’s calling a primary team with an update before they’re forced to page you. Sometimes it’s checking a postoperative patient because you have ten free minutes while everyone else is tied up in the operating room.

More often than not, it’s simply reducing cognitive load.

Your senior resident is simultaneously thinking about consults, operating rooms, floor patients, clinic, discharges, emergency department pages, and tomorrow’s schedule. Every task you complete without being asked is one fewer thing they have to remember.

The goal isn’t to look busy. The goal is to become someone whose presence makes the entire team more effective.

Accountability is another component of trust. When you take ownership of a task, the people around you should be able to stop thinking about it. If you say you’ll follow up on a scan, reassess a patient, or call a family, close the loop. Don’t make your senior keep a separate mental list of everything they’ve asked you to do because they aren’t sure whether it will get done.

You won’t always succeed. You’ll forget things, make mistakes, and occasionally realize that you didn’t do something you said you would. Accountability matters even more in those moments. Communicate the problem early. Admit what happened. Take responsibility for fixing it when you can, and figure out what needs to change so it doesn’t happen again.

Trust develops when people learn that your word reliably predicts your actions. Eventually, when you say, “I’ve got it,” the people around you should believe you.

Your reputation isn’t built during one impressive operation. It’s built through hundreds of small interactions that demonstrate whether people can depend on you.

You Have Five Years

Residency is a unique period in your career. You are given progressively more responsibility for real patients while still being surrounded by people whose job is to make sure you become capable of handling that responsibility independently.

You can commit to a diagnosis and compare your reasoning with someone who has seen the same presentation hundreds of times. You can develop an operative plan and have an experienced surgeon point out what you failed to consider. You can struggle through an operation until your attending recognizes that you need help and takes over. You can make mistakes, examine why you made them, and change how you approach the next patient.

That combination of responsibility, experience, feedback, and supervision will never exist in quite the same way again.

One day, you will be the attending.

Nobody will routinely review your assessment and tell you what you missed. Nobody will be standing across the operating table with more experience than you, ready to take over when you’re struggling. Nobody will make sure you learned from the complication, looked up the disease you didn’t understand, or corrected the weakness you’ve been avoiding.

The patients will still come. The difficult decisions will still need to be made. The complications will still happen.

The difference is that the final responsibility will be yours.

Residency gives you five years to prepare for that day. Five years to identify your weaknesses while you still have time to correct them. Five years to ask questions of people who know more than you. Five years to seek criticism, chase uncertainty, test your judgment, make mistakes, reflect on them, and try again.

Five years sounds like a long time when you’re an intern.

It isn’t.

Eventually, you’ll walk out of the hospital for the last time as a resident. The next time you walk in, you may be the person everyone else is looking to for the answer.

Don’t waste it.
