Tilt is probably one of the most important factors when it comes to poker. It doesn't matter if you play well or know all the percentages, if you lose a couple of big hands that you expected to win and you start make crazy calls or dumb bluffs, all of your hard work can be overturned. Just like that!

I used to tilt pretty badly, but I think I got over it. Idk, I haven't had a serious downstreak yet. I still curse when I should have had the best hand, or a worse hand beats me.

If you tilt too easily, hopefully you have the discipline to just walk away. If your in a tournament, tough luck. It might help to go out of your way to play more passively. Keep the pots small, its better than getting involved in large pots when your not in the right state of mind.
