Plus any decently intelligent, persistant and patient person can be a winning player, at least winning enough to make a living with it. Those who don't, lack some of these qualities and just shouldn't play. If they continue to do so anyway, it's their loss. *shrugs*
I play hell lot of poker, have a job and study at an university. Dropping studies for poker is stupid, but I doubt many people in these forums have done or will do so. What I'm trying to say that playing poker doesn't exclude ANY of the activies you described and it can also be done for fun (and even if you get your monthly salary from it, would you still consider it a waste if the people would be studying and/or going to a job the same time?).
Playing craploads of brood war might've been a mistake on some level (well... many levels probably) but it was for the entertainment value anyway, but yet again, it's a game that is played for fun and people don't need to quit college or univ or whatever to play it. I bet you're posting here for some reason too and I doubt it's because you don't play bw. This is a brood war forum and bw and poker have a lot in common and you're not better than any of us by not "wasting your life on games" so goan fuck yourself.
I'm so full of love today.
