I'm free to do whatever I want. I chose to learn informatics for the fat paycheck mostly. So what? I happened to like programming, nowadays I spend a lot of my free time building stuff for no reason, and have fun doing that. But in the end, if I were rich, I'm not sure I would be doing any of this. I would probably be playing ping pong all day long, or travelling around the world, or investing in space exploration, or learning astrophysics.
