...how I remember those halcyon days of yore. They sucked ass.
You sound like me: a smart guy (good LSAT), quasi-motivated undergraduate (although I somehow managed a 3.8), and generally more interested in enjoying my life and having fun than making a ton of money. Correct me if I'm wrong.
So do what I didn't: look before you leap. Take some time off from school to figure out what you're doing with your life before jumping into law school. Everything you hear about law school is true. Let me number them to emphasize how little you will enjoy this experience:
1. It is scandalously, exploitatively expensive. The amount of debt I have makes me sick to my stomach.
2. The professors, with very few exceptions, have no interest in teaching (especially at a top school like the one I went to). You're "taught" using the casebook method, which is a terrible way to learn anything, and generally nothing but a protacted exercise in hiding the ball. Studying using the casebooks is an extremely frustrating experience and I never got used to it. Class meanwhile is conducted in the Socratic method, which is intimidating and once again an exercise in hiding the ball for no good reason.
3. You are pitted against your fellow students. Because most schools grade on a fairly steep curve (only 20% get A's, typically), and because your GPA translates directly into the quality of job you will get, there is an intensely competitive atmosphere, and a social (or asocial?) hierarchy based on what kind of grades you got and whether you made Law Review.
4. You have to study your ass off to get good grades. There is no way around it. I may have been smarter than most of my fellow classmates by every other measure, but I generally got mediocre grades because I just couldn't put in the same hours in the library that they did. I didn't see the point in giving up my life like that.
So, don't be dumb. Rethink this law school thing. I made it through and I have a job I enjoy now (thankfully I'm not at a huge firm working 80 hours a week), but it was a harrowing experience. My boss, who went to law school 30 years ago, recalls the whole experience with such ire that he won't answer the phone when law schools call asking him to come to career fairs, etc. The whole law school system is exploitative and needlessly painful.
