Dude, San Fran is like the most expensive place in the universe.

Go to college, if you can, and study something that will bring you the $$$ to afford you the opportunity to be your own boss some day.

Otherwise, find a friend and move to Orlando. The jobs are crappy but there are allot of them.
You won't starve to death and maybe you'll find what you're looking for. There are allot of cute girls, also.

If you like video & music production, Full Sail is a world class school for it.
