How can I protect myself third year from getting screwed?

I will be starting rotations in a couple of months and would like to know how to best protect myself 3rd year. I've heard way too many horror stories from people about how they they've gotten screwed.

Aside from being on top of my game by reading every night after work and doing questions on Uworld CK and Kaplan, what else can I do? I'm looking for specific advice not general aphorisms such as "being nice, helpful, etc"

I apologize in advance if this is a redundant thread. I'm sure this issue has been discussed numerous times in the past. If someone could point me to the thread where this has been discussed, I would appreciate that as well.

Thank You!!
