There's lots I would have done differently, but here are a few things off the top of my head:

I would have taken a semester/year to travel abroad before becoming an attorney. In that same vein, I wish I'd done something of service like Americorps before saddling myself with student loans from law school. But if I'm really rewriting my life, I would have become a journalist/writer instead of a lawyer.

I would have taken more risks, e.g., I would have moved away after law school and just hoped for the best. I'm a very cautious person and I think that, more than my abilities or skill set, has held me back.

I would have spent less time crying over ex-boyfriends and more over lost friends.

Of course, I would have taken up cycling and yoga a lot earlier.

I would have volunteered more.

I would never have gotten a tv or cable. I didn't own a tv for a long time and regret that I ever bought one (I know, I know. What's stopping me from getting rid of it now.....) Instead, I wish I would have become an NPR junkie a lot sooner.

I wish I'd recognized when I was younger that I didn't need to know all the answers, that I didn't even know all the questions and that I should have just relaxed and gone with the flow a lot more. It's great to be driven and to have a plan, but I think you also need to be open to surprises.
