I take a short break if my tilt starts to stop me from playing, ideally to finish the game on this day, but if you need to finish playing a couple of tournaments then try to distract yourself with music or a movie
I find talking to yourself helps. Talking through your moves and telling yourself it was a good fold or a good call etc. I think it helps so your emotions don’t take control. This way your head is still in the game so to speak.
The Mental Game of Poker by Jared Tendler covers just about every form of tilt and how to control it. Once you get that down pat, you can predict how your opponents tilt will effect their game! ;-)
Understand the nature of this game: If you roll a die, you should know that you can not control the results, in poker you have a little more control, but even you are the best player around the world, you will lost many times. A lot of people loose their minds for bad beats, but this often happens because thay are playing out of their bankroll management. A lot of people ignore how this game is uncertain for a hope of a day hitting a big prize, but without a planning, skill and money, their prizes aren't enough to direct their chart up.
for me a way to overcome the tilt is understandable that you can always have a bad beat but you get over it quickly to stay focused and keep playing your best poker
