Well, you can learn something I call "business art". Basically, it's a simple rules how to start own business

. Start it from zero
Instead of buying the cart you can rent it. Zero risk.
Learn how to run your business first and create simple (for beginning

)business plan. You don't need to buy any books to stady, there are plenty of sourses in the Internet!
Try to start only with own money, and reserve some of them in case your business is not going well. Always try to minimize your expenses, be creative minimizing

.
I'm going to start my own business now. I have something to sell: I'm doing art. Business is different than just to do art, oh. I' like a few persons at the same time: marketing research, designer, assembler, accountant ...everybody.So far I spent just $100 to start. I need just $150 more before I'm coming out with the product to sell. $250 isn't a big loss in case I made mistake.
Also, I desided to look for part time job after I finally make a few of my own designes of jewelry (hopefully, bestsellers

You can look for part-time job for now.
After you "tasted" own business it's hard to work for somebody else.
P.S. I was fired last week due to overqualification. F*ck them!
