A half hour of play a few times a week will make you decent after a couple months.

will you be getting sponsored by Red Bull or some shit? prolly not, but it def ain't too late to learn.

i play a lot. i spend like an hour after work playing. i still ain't very good, but i've gotten to a place where i can hang with high level players and that's all i want from it. but you don't even need to play that much to get to a level where you're enjoying the games.
