I see alot of dota players in my college swearing like nobody's business and most of them also phail in their studies

anything can be made into your career but what matters is that how long will it last...look at the TOP players in World Cyber Games(WCG) for example..there some of them who are paid to play and earn salaries like everybody else...and some of the players also have degrees like us in a certain field...and also in football david beckham for example...he has a degree in medicine...i doubt that all gamers are 'rich fellows with no brain'..because if they do not have brains..how are they gonna play the game...playing a game also need brains
