I've adopted the belief that very, very few people in the startup world were born with a passion, or at least developed one at a very young age. Even those who claimed to have developed such strong interests from a young age that later influenced their success, I find hard to believe. It's easy to romanticize the past and connect the dots in hindsight.<p>Here's what I think: You can develop passions when you realize that the problem you're onto is a meaningful one. I think when you truly believe that the solution you're trying to provide genuinely helps people, you grow a passion not for the specific domain your startup is working in, but rather for the idea of solving a big problem. Growing a deep interest in how a particular domain works is secondary and required in your pursuit to solve a problem.<p>I don't think anyone at Stripe has a genuine passion for the technicalities of online money transactions, but I do believe that they know they're addressing a huge pain-point that many, many people have been forced to deal with. They know their solution will be meaningful, and so they'll try to dig as deep as they can into that specific domain so that their product is better tailored for their given problem. I could be wrong. I think pg's recent essay on Schlep Blindness touches on this as well. If you develop a passion for solving problems, you might open your eyes to many, many more opportunities, versus if you directed your attention on finding that one domain that really sets your candle aflame.<p>But, I do struggle with that question on an almost daily basis. While what I stated should provide encouragement in that passions and deep interests can be developed, I can't say I'm not jealous of others I see who have seemed to genuinely take a liking to a specific subject, so much so that, startup or not, they'll chase their dream and be happy doing it.
