Many people would like to be self-employed but fear the risk -- with good reason. Within five years, half of new businesses are out of business.

Ironically, you're particularly likely to fail if you follow such standard business school exhortations as "Innovate!" While such advice makes for interesting class discussions and may be appropriate for "intrapreneurs" inside deep-pocketed corporations, it puts the average entrepreneur at grave risk of going bust.

The key to maximizing your chances of success is to do the opposite of what is taught in business school:

1. Don't innovate; replicate. Being a guinea pig is so risky: Your idea or its execution could easily be flawed, or it can be so new that the public isn't ready for it. Tivo, an unquestionable improvement over the VCR, lost hundreds of millions of dollars in its first five years as it tried to educate the public. You probably don't have hundreds of millions of dollars and five years to wait for profitability.

Instead, clone a simple, small-investment business that, in multiple locations, is successful. How can you tell? Check out retail shopping areas. Which stores are busiest? When I did that recently in the San Francisco Bay Area, I found that burrito joints are booming. The Bay Area is very anti-establishment yet needs fast food -- burrito joints are perfect.
