I think the biggest key is don't just get a degree or attain the knowledge, then make the mistake of just getting hired to Google or Congregate gaming or anything like that where they own anything you make. You're just making the same mistake everyone else is, you're just working for a living / doing a job no matter if you're making 80k a year or 250k a year. Do it independent. It'll be pretty hard to get started and it'll be a long shot, but the success will be exponentially more if you do succeed, and working hard for yourself while it's brutal is something actually worth doing especially if it's something you're passionate about
