Thanks for the response. I actually have some limited classroom experience so know a little bit about what to expect.

I suppose the main concern is changing directions in my career. I know a lot of people change careers often, but... Well, I guess my anxiety stems from this: since I've determined that my original career path (from my undergrad degree and a master's I'm currently completing) is not for me, I'm worried about making another wrong choice.

What if I try this path, thinking it will be a good fit, but I end up unhappy in it as well....
