From UNC Asheville’s web site:
What advice do you have for students who wish to start their own business?
Start several. Seriously. If I could go back and do it over again, I’d start the smallest, easiest business in the world—like a lemonade stand or something—and make that wildly successful. Then move on to a business that’s a little bit harder—a lemonade stand franchise—and make that wildly successful. Then start a software company and try to raise venture capital, acquire patents, that kind of thing. Setting attainable goals and outperforming is much better than setting unrealistic goals and failing.
