Kind of reminds me of something Richard Feynman said: "Then I had another thought: Physics disgusts me a little bit now, but I used to enjoy doing physics. Why did I enjoy it? I used to play with it. I used to do whatever I felt like doing - it didn't have to do with whether it was important for the development of nuclear physics, but whether it was interesting and amusing for me to play with. When I was in high school, I'd see water running out of a faucet growing narrower, and wonder if I could figure out what determines that curve. I found it was rather easy to do. I didn't have to do it; it wasn't important for the future of science; somebody else had already done it. That didn't make any difference. I'd invent things and play with things for my own entertainment." I think we should take serious stock not only in what Notch is saying here but also his overall success: if you get off making ephemeral photo-sharing apps or a Salesforce clone then keep on trucking otherwise you should ask yourself why you're doing it in the first place. Are your little projects a ton of fun to work on? Notch makes an all around good argument for pursuing your passion.
