Instead of calling it a problem, i would prefer a much more interesting term, challenge ex.
Many non poker related persons struggle extremely on how they react and act to others, and things that dont go their way.
It has never been about finding the problem, because that is kinda obv. Its about finding the solution, with curiosity, and try to understand why it is so hard to accept things as they are, and instead be happy for others, instead of letting the mind go haywire (spelling ♦).
Its actualy all about patience, commitment to finding a solution in a good structured way. Erik stenqvist has some wise words on this saying - by many other things - that it is not cured by beeing result orientated, but about the effort you put in to the challenge.
Sometimes i find myself doing and effort in a paticulary area and completing the challenge 90%, then say to my self it is done, but actually i have come to the conclusion that if a challenge occurs in front of you, and if it is extreme, the best you can do is look how you can use it to your own advantage. Ex: you 24 tabling cg and are up 4 bi kinda fast, i often look the thinnest marginal spots to bluf / valuebet / cr / 4bet light etc.
Back when i was playing sng, and suffered a big upswing, kinda got me auto adjusting to taking extra advantage of the up swing, which led to unreal up swings, and too long downswings. Literally changed my A game so far away from the original winning game, so that i got unsure if i still beated the sngs.
And all this leads back to beeing result orientated, which can never be a good thing if you expect something to happen, and then it dont, which leads to tilt in forms of a non acceptance of what was happening, which leads to simple variance. Thinking back what i did on my own before i trained meditation was to keep playing nomatter how hard i tilted, maybe that costed a few bi or 2, but i came to the same conclusion every time playing through tilt, "I am winning in this game, i need to improve, i wont improve into a real boss if i cant control my emotions' took a deep breath, thought what i did wrong, why i did what i did, and why i wasnt focusing on the cards and dynamics accumulating, but instead in my own feelings. All this in a few 3-4 sec, then back grinding like if i just started the session from scratch"
The challenge i closed thinking i've had come out with possitive result, was to structure out ALL grinds, ALL emotions during session (yes that only made it possible to 6 tabling because i was also sitting with pen and paper to write down everytime i thought i was out of balance, how me and my body reacted, and why i thought it came out that way.
Goals for the session pokerstrategy wise, goals for the session tilt wise on paper everytime before i started.
ATM i tilted horribly yesterday, but i have also been slacking in effort on the challenge of improving as a person and grinder. (The 90% rule of always thinking i am done with the challenge) So now im gonna work a bit before grind today 
If you are a particular person that tend to get caught up in your own emotions, it can (in my exp) maybe be so extreme that their dont seem to be a cure. But that is like saying, BLA BLA I WONT TILT IF I DONT LOSE WITH SET OVER SET. There is though a way to reverse the tilt, and to find it early enough, so you dont have to quit the session, but instead "tuning" in to the right state of mind. That requires selfobservation and a calm/alert state of mind.
Saying you are cured/dont tilt anymore, is like ignoring a challenge that might cost you in the longrun.
Some nl1000 players tend to think: ok he just lost i bi so now he might be on tilt, and maybe he defend much lighter if i 3/5bet again in pos this time, he might spazz out and say screw it, and ship it all in, so now i fold my 43s.
But what if it was possible to play EXACTLY like you did before you lose your bi on bigger stakes? Thats all about giving it a meaning, that dont include results.
Nice thread
