5 different careers!?

I was thinking for a couple of months about this, and I'm deciding to do it. I'm going to attempt to get 5 different careers. The order I want to pursue them in is: chef, mage therapist, hair stylist, mechanic for fuel cell cars, and finally computer tech. If you think about it as well, you would see that I would seldom have to go anywhere and pay to get anything fixed. Good food, check; sore muscles, check; hair, check; car getting fixed, check; computer problems, check. Now I want to know what you think about this. Thanks!
