I was a CS student by day, who hated classes, so I went home at night and instead of doing my homework kept trying to learn iPhone development, not because I wanted to do iPhone things, but because having an app on the App Store seemed like it would be super cool. Long story short, a friend of mine was going a PHD in cognitive psychology, and he was big in the statistical analysis crowd around Major League Baseball, so he got me data of their heat maps for strikes and balls of every hitter and pitcher. We turned it into an app, at $0.99, so after two sales we had earned our first dollar. We went on to make a couple thousand more off that app, and nowadays I'm do that iOS thing full time.
