Well do you have any money? If I had to do it all over again I would travel. Then I would work just because I find myself more motivated in school after working. As for what to do.. why do you want to do?

Personally if I had it to do over again I would look for some sort of teaching job. The job is stable... you probably won't get fired, you get summers off and you get a pension.

Second on my list of do overs is starting my own business. This is the time to do it, when you have little to lose and lots of energy. What kind of business.. for me it would be something to do with real estate but who knows. If it fails now you can just get a job and it would look good on your resume.
