Given your stats, I'd say you have a very good shot at being smart enough not to go to law school.
didn't you clerk? I thought you liked the law...?
No, I don't like it, I LOVE
it. It has worked out very well for me - I can't think of a thing I would change. I have a hard time seeing it as a good investment nowadays, however. You really have to want it, and you have to throw any sense of entitlement you could've gotten away with in years past out the window. I'm not saying you don't want it or you do feel entitled, because I don't know you, but I do know a significant number of recent grads disillusioned due to one or both of the aforementioned factors.
If you're sure you want to go to law school, then your stats indicate the work ethic and intellect to get in somewhere great and succeed there. But I've heard rumors that even at places like Columbia, students in the bottom half of the class are having a tough time on the job front. That sucks for a school at which you'd likely pay full price. And as smart and hard-working as you are, all of your classmates there will be too. It's just scary.
But, then again, it's not like all of your other opportunities are likely to be economically rosy, either. So do what you must, and best of luck to you.
