Making friends in law school is similar to making friends in real life.
The distinction, then, lies in the pool of potential friends: it is slightly homogenized in comparison.
Is everyone in law school an archtype?
The moment you enroll in law school you already share a number of commonalities with your first-year class. This is because law school appeals to only a handful of personalities: the hard worker, the go-getter, the do-gooder, et al. Of course, law school is only a means to a professional end, but neither is for the faint-of-heart.
I was tempted to write on the typical archetypes you are likely to encounter in law school (and how to navigate among them). Most books on surviving/succeeding in law school do this (e.g. “the gunner”). You can read these books.
