Agree with everything in the OP except the "make love, not law review" part. I would strongly advise 1L's to make allies, not friends.
Lawyers as a whole might be mildly interesting/entertaining people, and I grant that finding a few great folks in any sampling of 200-300 people is virtually a mathematical certainty. But far too often law students turn into cardboard jackals who will sell you out for a marginally better opportunity to acquire a condo and a swimming pool. It's all well and good for the first few weeks of school, but things like "I'm glad X is having family problems and missing class because that will lower the curve for the rest of us" become more the rule than the exception as the semester winds down. Why waste your time and energy forming substantive bonds with people like this? Divulge enough of yourself at mixers to ensure that you're not bored on Saturday night and will be able to garner business referrals in the years to come. Respect the fact that everyone else is working hard and that everyone will need a helping hand once and a while. Know that your classmate's attitudes will likely improve as time goes on. But anything beyond ally-forming is a waste of time, especially during the first semester, unless you're lucky enough to find the handful of people who you somehow know won't succumb to the anxiety of competition.
