Just to add a few huge tips that i have to use for myself is

1 DONT PLAY TIRED! i work anywhere from 8-12 hour shifts and after a long day i stick to easy fun games that i can enjoy winning or loosing
2 DONT ARGUE IN CHAT! as a long time gamer i am known for shit talkin on alot of what i do ( more for fun not for rage) But accompany it with a bad beat and my whole mood goes down hill.
