I remember the week before intern year. I'd crushed shelf exams, gotten solid evals, done everything right.

I was not ready.

Not because I didn't know medicine — but because nobody teaches you the other stuff. The stuff that actually determines whether you survive or spiral.

Here's what I wish someone had told me:

1. Efficiency on the wards matters more than medical knowledge.

Most interns know the diagnosis. Few know how to write a concise note, pre-round in 45 minutes, and handle 12 pages before noon without losing it. That's what makes intern year brutal — not the medicine.

2. Night shifts don't destroy you. Bad night shift habits do.

The mistake is treating post-call days like free time and winging your sleep schedule. Your circadian rhythm will fight you. There's a better system — and it makes a real difference.

3. Your relationship with nurses matters more than your relationship with attendings.

Attendings see you once a day. Nurses see your patients all day. If nurses trust you, you get called about what matters. If they don't, you get called about everything at 3am.

4. Residency reshapes your identity whether you prepare for it or not.

Most residents don't realize they're changing until they already have — and often not for the better.

I wrote The Residency Survival Guide to cover all of this. Not theory. What actually works when you're running on 4 hours of sleep with 18 patients to round on.

If you're a med student about to start intern year, or a first-year resident trying to get through it — this is for you.
