I sold my first app at 16 and cofounded a company that earns about $30 million a year. One of my biggest challenges now is finding people I can relate to in college.

I sold my first app at 16 years old for almost $100,000. It was called Totally Science, an unblocked gaming website that allowed students to play games in school. It earned me thousands a year for two years through Google AdSense before I sold it.
