It's because most of us are curious individuals. I had a lot of interests: coding, playing musical instruments, cars, woodworking, embedded systems, audio/video engineering, etc, but I had to pare it down to just a few after having had several bouts of burnouts. I'd recommend trying 200 interests at a shallow level, and eventually you'll find some of them are more interesting than others. And then start to focus on the few that you really want to pursue, or those that actually move the needle of your ultimate goals in life. I'd recommend the book "The One Thing".
