In baseball, you have to remain calm, cool, and collected. In football, you can let out a little anger sometimes. It was a fun game, and I liked it, but I knew in my heart I was going to play baseball.
I talked to a few schools about playing football, but I had already pretty much made my mind up. I fell in love with baseball at a young age, and I knew that that's what I wanted to do.
I always knew I wanted to be a technologist, so I went to Duke and got a degree in computer science and electrical engineering. Really, I thought my goal in life was to be an inventor, a problem solver, so I thought I needed a Ph.D. to be good at inventions, but it turns out that you don't.
After building most of Mint.com's prototype by myself, I talked to anyone and everyone I knew about Mint. It's counter-intuitive, because you might fear someone will steal your idea, but it's the only way to make connections, be sure you're on the right track, and provide a solution for an audience broader than yourself.
Kevin Systrom of Instagram used to work for us as a consultant in the early days of Mint. I knew him a long time ago. Maybe I could have gotten in there. But with photo sharing, I don't know if there's an obvious business model. I don't think there's a competitive, sustainable advantage.
At 16, I started a web development business and had clients from the Netherlands, Caribbean, and across the country - none of whom knew my age because I could conduct all my business with a phone, scanner, and the Internet.
Carefully calculate the potential size of your market to make sure you can grow. Before starting Mint, I knew that there were about 20 million people who had purchased 'Quicken' or 'Microsoft Money' over the years, and 80 million people using online banking in the U.S. alone.
I never really got paid for 'Tell It Like Is,' but I look back at it and say God knew what he was doing; he probably figured that if I had got money back in them days, I wouldn't be here now. That's okay. I'm here. And I'm still singing the song.
I think by eighth grade I knew I wanted to be an actor. I'd done church plays and stuff, but my first actual acting class was in eighth grade. I was obsessed with it.
