- Don't sell out. Find out what you love whether it's design, programming, assembly, hacking stuff, building stuff, whatever... and do that.
If you sell out, at the beginning you might make loads of $$$, it'll be amazing, maybe you'll make more than your dad ever made, maybe you'll buy yourself a 70" TV but trust me... 3 to 5 years in. You'll be that annoying guy that tells all his friends he sold out and really wished to have been an actor, a sportsman, an artist, a musician, an animator.
- Save enough $$$ for 6months of living without work, all of a sudden you'll be a lot pickier on what you work on.
