Hey, read All I Really Need To Know I Learned In Kindergarten.
Cheesy stuff that is not law-centric? Sure. But I think it'd be great if law students came in remembering to "share and play well with others."
If you are going to read the pre-law prep books, read the section on how to not be hated by your fellow students -- don't argue with a professor just to prove you are right, do not hijack discussions in class, etc.
Together, we can create a kinder, gentler law school.
