I always play unconventionally when it comes to competitive games, it makes them more fun 
I've tried this before, It works in some games.
Playing like you don't care about winning, maybe like in TF2 when you play spy and sap the same guys dispenser all game regardless of how far behind your team is.
Or troll building AP malphite on league of legends or something. Doing unconventional things always helps it seems.
It makes it seem like I wasn't trying on purpose. If that makes sense...
To be fair when I saw this thread and saw it was you pandan I was gonna be a richard. But since you've came back whenever I've seen you around you seem like a pretty cool guy.
Back on topic. When you get mad about things I find it best to just step away from it. I end up getting into huge arguments with people because I just keep going. I keep getting angrier, mostly due to just arguing. It really helps when I just step back and try not to think about it. Even when I'm doing something and start getting pissed about it if I step away and come back later I feel so much better.
I appreciate the honesty, and the advice.
Yeah a lot of you are saying to step away, and I try to do that sometimes. But my ego gets in the way, and I don't want to let the other guy win. Which is part of the problem.
I've decided to stop playing so many competitive games. And if I do play them, I guess I just need to not give a stuff if I step away from it.
I've been reading every reply. So none of the advice is going unnoticed. Thanks everyone. Exploration is important for finding a solution to a problem.
