I know how you feel, my parents tell me not to spend my money on stuff like that, but I kinda have it figured out. If I want to buy something, like my dirtbike I bought last year, my dad would let me spend my money on it. If I wanted to buy something like a cell phone or,(this may sound extremely dorky) a video game, my mom won't care and my dad thinks I'm nuts. But like pure, as long as I live with my parents they pretty much decide how I can spend my money. So maybe I should move out ;)
The greatest enemy to what you can know, is what you already know.
It's not how good you play, its how well you play it.
