Here's a short excerpt from the interview:
Really. There’s whole notion of “drift” that I think a lot of people fall into with law school. They don’t decide, necessarily, to go to law school, but they drift into it, really for lack of a better idea.
And I think that’s one of the reasons so many lawyers are unhappy. They hear these lines that, on their face, seem to make sense: ‘It can’t hurt to take the LSAT.’ ‘I can always go to law school.’ ‘I can always change my mind later.’ That’s what happened to me. I drifted into it. My father is a lawyer, and he’s very happy, but I didn’t give it a lot of thought. Then I got into Yale, and thought ‘wow, this is great.’ And I did well at Yale. Each step of the way I was like ‘wow, I’m editor-in-chief of the Law Journal, that’s cool!’ And then it was: ‘a clerkship with Justice O’Connor! That’s fun!’ But I really had no plan, no vision.
