Yeah, it's even a waste later on. I could have been a middle manager, at least, if I'd used all those thousands of hours I spent managing teenagers in Dota 1/2 and WoW to work on my career or do sports or read or whatever...
I reckon so. I got an Xbox in 7th grade. By the time I was in 9th I was devoting all my free time to Halo and such. Could have been working or playing or riding a bike or a myriad of better things that'd have bettered me somehow. Instead... I can double shot and no-scope well.
