Well I have the same thing going on. It's quite a feat if I can keep a job for more than half a year or so. Temp jobs, housekeeper jobs, retail, kitchen jobs, you name it.

I am in a position though that I can work freelance as several things due to my background, and I did that for a while for extra cash, but now I am making a one man business out of it. I figured that if no one wants me or wants to keep me, then I will become my own boss.

It's a bit of a risky option, but I can always stop if it gets too much, and I won't have a hole in my resume.
