Trying so Hard without payoff!

I am putting 100% into trying to work on my relationship with my son but the more I do try the more I see that I just don't like his behavior and the person he is. Last night I tried to show him he was doing his work wrong and no matter what I said he though he was right and he put 100% effort into the work but when I checked the work it was not even complete and worse for all it was not right!
He has a baseball game tonight and then I told him that on Tuesday nights I am trying to make it so that I can spend more time with him but yet I am not looking forward to it because I know he is going to do something that is going to totally make me annoyed at his behavior.
How do I get past these feelings?
