On a more serious note. Just write about how the diversity, good teaching, and diverse patient population will make you a better ...ist (specialist).
Look, let's not kid ourselves here. These people don't need you to publish or give money back to the program. Your scores will get you through the door (before I matched I would have told you that they are the only things that matter- which they don't). Then it's up to how well your interviews go.
Just shmooze, smile a lot and make it seem like nothing bothers you (because that's what they're looking for, somebody that can roll with the punches).
At this point I would say they don't really care if you're a genius, but more of a work horse, that can also get along with people. That will get you a long way.
So basically I wouldn't be spending my friday nights in drafting different versions of your transitional year statment. Spend it on your categorical app part.
btw, same applies for prelim (medicine/surgery/other). Just spin it a little differently
Medicine - I want to really learn about differential diagnoses and round
Surgery - I hate rounding I want to learn how to do less with my brain and more with my hands.
OB/GYN - why would I ever IN THE WORLD want to do this to myself (answer it yourself)
Peds - Children are the future of the world.
FP - I am very touchy feely, and kinda dorky.
ps. These are just jokes people...hahaha...
