What do you like to do? I couldn't do a 9-5 reg job behind a desk or anything. So I do a few diff things that I am good at and enjoy and aren't so life depressing.
I always vote for starting your own biz: take an inventory of yourself- what do you like to do? Are you good at it? Are you great at it? If you took a course, got certified or apprenticed for awhile would that help your proficiency or make you seem more valid? How can you fill a need with your product or service? Would you still enjoy doing this if you have to do it for a living? its easy to get burnt out.

Start there and just brainstorm. Write everything down no matter how ridiculous, every idea can lead to a great bankable one. Don't settle for workin at the hardware store if you have yearning to be free.
Good luck
