You are enormously wasting your time. Because you chooses to go into some inadequate custom game, it shows your lack of motivation, initiative and because you chooses to do this, you care more about wasting your time than your own success.

But, more specifically, since you are a competitive gamer, you don't get to take breaks and waste your time, that's what a casual gamer does.

A competitive gamer actually wants something out of his life, he or she actually wants to do something with his career.

Now even though you claim to be a competitive gamer, you act like a casual gamer. Now if you don't care what I'm saying, he can keep wasting your time and continue to put wasting time over success.

Now ultimately it would be a contradiction to call yourself a competitive gamer when you really aren't one.

Now if you do want to take what I have said into consideration, then you should ultimately be changing your work ethic

and any professional will tell you that the beginning and middle stages are where the most dedication, work and commitment have to be put in.

It's like a bodybuilder who wants to lose fat, and he has to have a strict diet and has to cut the majority if not all fatty foods that he eats in order to lean out so he can build muscle.

But once he gets to where he wants to get, weight wise, cutness, toneness, body size... then he can start to eat those moderate fatty foods after he has reached his goal.
