I'm about to quit my job,take some time off, then maybe move to SF. Any Advice?

Or ideas to work on?

I'm burned out at work and really need a break. My life needs change and I'd love to feel the joy of programming again!

I plan to use PHP and Javascript, as well as learn Python. Websites, applications, games, whatever.

Ideally I'll create stuff that is demoable and perhaps useful.
