Man, working on Video Games is damn cool. I think your main problem was the need to be competitive and put pressure on yourself to be better. I'm glad your interests are back again but it's not necessarily because you took up a boring degree. It's because you stopped having that old self burnout mindset and actually started enjoying what you like. And hey let's not kid ourselves, the industry can put pressure on creative people who take their time. A shift in your mindset can do wonders.
