Why a video game? Do you really have time for video games?
How many hours of video games should I play a day to be good at it?
Hours? Why would you want to waste so much time on video games? There is more to life than sitting on your ass working your thumbs. If I remember correctly Zack, you were interested in soccer. That or another activity would be WAY better. My father used to smile and say, "Why don't you go outside and find something to do? Maybe the fresh air will blow the stink off of you."
Squandering time at a pointless pursuit. You get good at a video game, what then? Play another one? What have you achieved?
Go learn an instrument, play a sport, make some friends, make some art, ride a bike, read a non-fiction book, explore nature.
The world is passing you by while you park in front of that screen, doing the same thing, over and over, to no avail.
What a waste of a life.
You should socialize more
