A recent study by the Ewing Marion Kauffman Foundation, titled Anatomy of an Entrepreneur, found that more than half of entrepreneurs had an interest in entrepreneurship in college. In addition, of those who said they were "extremely interested" in entrepreneurship in college, 47 percent have founded more than two companies.

Challenging the common theory that entrepreneurship increases during tough economies as a solution to layoffs, the study found that only 4 percent of entrepreneurs cited "inability to find traditional employment" as a factor in starting their business.

Instead, entrepreneurs tend to run on ambition and independence - the primary factor in starting a business was "building wealth," followed by "capitalizing on a business idea," "the appeal of startup culture," "desire to own a company" and "lack of interest in working for someone else."

The Kauffman study findings are in line with the June Discover Small Business Watch, which found that "needing a job" was the least common factor for starting a business.
