Question 8: Do You Have A Concept You're Passionate About?

Every morning you want to jump out of bed eager to get to work. If you're not that exuberant about how you'll be spending your time -- or the business concept itself -- running a business is going to be a rough ride.

Ms. Ettenson of the Association of Small Business Development Centers has coached many prospective entrepreneurs about their chosen business. She always asks why they're doing it. If they suggest it's mostly for the prospect of making a lot of money or because they're tired of working for someone else, she steers them toward something more in line with their interests or avoiding self-employment altogether.

"If you hate doing paperwork, the last thing you want to do is become a bookkeeper," Ms. Ettenson says. "If you'd rather be outside taking people into the wilderness, then that's the type of business you should be in."

But it's also usually wise to find a business in an industry you are very familiar with; it will be much harder to succeed if you know little about the field. Mr. Fishback at Kauffman says he has steered a doctor and other professionals away from starting restaurants because they often don't grasp how difficult and risky restaurant ownership is. And they'd be competing against restaurateurs with years of experience.
