If something is scary or difficult, I want to be so prepared that it is no longer scary.
Another personal round. This one got into life lessons, nerves, and the best and worst career advice I've ever been handed.
A few things, and both of these lessons I learned from patients early in my career, right after I finished training.
That sounds blunt, and I mean it kindly:
We're all aging. You really need to learn to appreciate what you see in the mirror, and to see the blessings in your life, because you just get older with time.
I learned that from patients, which is maybe the one credential that makes it land. (It's also why I think so much about the difference between wanting a change and being told you need one, and why there's no age at which it stops being your decision.)
The second one I'd tell my younger self: the things that are important should all be given the same amount of energy.
Maintaining friendships and relationships with family should be as important as your career. And that was not always the case for me in training, because of the hours I was working. Surgical training does that to people.
If I could go back, I would spend more time on some of those friendships.
Before a really big surgery, or something complicated in a way that's different from a typical procedure, I handle it exactly one way: I over-prepare.
I've been this way since early medical school.
If something is scary or difficult, I want to be so prepared that it's no longer scary.
That's the whole trick. Nerves aren't something I talk myself out of. They're something I out-prepare.
I come from a family of physicians, so when it comes to career advice I had never-ending troves of it. Two pieces stuck:
Treat every day like an audition. Make sure you're at your best at every moment of every day.
Take every opportunity and cherish it, because:
There are a million people just as smart as you are waiting for every opportunity you have.
Understand that, and be respectful of the gifts you've been given.
This one I actually overheard being said to a different resident, and it was:
"You are not replaceable, and you're incredible."
Here's my problem with it: we're all replaceable, and I think we all need to recognize that.
It's worth noticing that this is the same belief as the good advice, just pointed the other way. "Treat every day like an audition" and "you're irreplaceable" can't both be true. One of them keeps you sharp and grateful. The other one makes you complacent, and complacency in an operating room is not a personality quirk.
Four honest answers:
If you want the lighter version of this, the previous personal round covered dog portraits and my Sunday scaries routine, and there's a whole rapid-fire personal Q&A if you're curious about the rest.

Hot Takes: Dog Portraits, Sunday Scaries, and Why I Answer Comments
September 7, 2026
A personal round of hot takes from Dr. Killeen: the money she spent on portraits of her dogs, her deliberately boring Sunday scaries routine (Pilates, laundry done, takeout, early bed), the audiobook that made her tear up (The Correspondent, recommended by a patient), and why answering questions on TikTok has made her a better doctor, because patients ask things online they would never ask in the office.

What I Look For When Hiring a Nurse Practitioner
April 4, 2025
Dr. Killeen explains what she actually looks for when hiring a nurse practitioner for her plastic surgery team: a background with real autonomy (ED, L&D, ICU, or surgery), genuine curiosity, a strong assertive personality that can hold a discussion with her, and above all the difference between problem solving and information gathering during the trial period. Plus why good vibes genuinely matter when your team is a patient's biggest cheerleader.

Yes, No, Maybe: The Personal Questions You Actually Asked Me
July 24, 2026
A personal rapid-fire Q&A with Dr. Killeen — whether she automatically sizes up chests when she walks into a room (no), whether she has ever faked being bad at something so a patient would stop asking (never with patients, occasionally at parties), whether she has ever cried in the OR (no, that is when she is calmest), the patient she still thinks about ten years later, and the one time she was completely starstruck.
