I'm really, genuinely happy for you that the thing you're passionate about is something you're good at and is extremely lucrative, but if I tried to make a living doing what I'm passionate about I'd live in a cardboard box. The reality is that software eating the world (and admittedly a number of other things, but this is a big one) have made it much, much harder to make a living doing just about anything else. I got a job in software development because I was good enough at it and I needed to pay the loans from pursuing my passion. I continue doing software development because it's a way to eventually maybe escape capitalism without swallowing a bullet.
