That is not exactly true. It's a virus idea that was spread by 37signals. Sure, it's great to work on the thing you love and get money for selling it. But that's not how it should always be. There are a lot of businesses, where people just make money. Like for example that recent post about the guy who made 38 millions on selling postcards. What's so bad about this? He now has enough money to finally do something he really likes and not think about the profit at all. So the bottom line is: it's different. Should I miss the opportunity only because it's not something I'm passionate about?
