in one way it is true what you say ...
but think other way , what would be life without enjoying it ..
i mean i found 8years ago , 7 friends in a random cs:s match ... and since then they are my best friends we even meet on LANs ... i can tell them everything and they even help me in hard moments ..
i mean, ofc you spent "hours and hours in gaming" but without gaming you would prob. go out and do other stuff with your friends ..
i dont think its a "waste of time" if you got something you want to reach in gaming .. me for example, i want to reach to get pro player, 5 years ago we started to try to get into semi pro series, 1 year later we are in ... actualy we are in 3th div. ..
i love to play and i enjoy it, i hope you do the same, its your hobby, dont waste your life in stuff you dont like to do (beside work/school .. you have to go for it , no joke^^)
... nice topic !
