What do you do to prevent tilts?

If I'm starting to tilt, i just close the game and do something less frustrating, like trying to teach my cat to play fetch.

I turn my console on and play some good old fashioned elder scrolls.

I take a damn break. You don't go on tilt if you aren't playing!

Personally, It takes on average two bad, HORRIBLE, games for me to begin going on tilt. So, after those games I do some programming, listen to music, and relax for a while. Playing on tilt is a terrible idea, you get too worked up over a game that you don't learn from your mistakes anymore. That's wasted time if you ask me.

I made a rule to myself that I take a break after 2 ranked losses in a row. Then I either go have fun in some normals or I go do something relaxing.
