You watch TV? You play video games? You do random junk shit hobbies that in ten years time you won't have anything to show for it except possible average memories?
If I had spent the thousands upon thousands of hours 3Ding and animating instead of playing video games in my life, I would be a master of all. I'm still very accomplished in 3D but I know that these things have no meaning except enjoyment. I want more out of life, I want accomplishment in doing something I have loved since I was a kid. I've gotten into the games industry, and now I'm prototyping a bunch of game ideas to see if they work.
If any of the things such as past time hobbies apply to you, do what you want to do that could easily mean something in 5-10 years.
