Very nearly missed my plane to Pennsylvania. When they check your ID at the airport, make sure you put it back in your wallet instead of the security basket, folks.
I very much thought that I shot myself in the foot at my Tufts interview. It's hard to keep perspective, so don't worry too much after the interview (I know that's nearly impossible to do, but try).
In hindsight, research was not a good idea. What I should have done was more clinical experience, since that's what I based my application on. I had said that I want clinical medicine, not research, which brings up the question: 'Well, why are you doing that in your year after graduation, instead of driving an ambulance somewhere?' I had a good answer (I know this because I have done research), but still. Know your app.
Don't be lazy, act early. Taking a year to do something else and get all my ducks in a row was an excellent idea. Good luck!
