overanalysis causes anxiety..
The only sure cure for poker anxiety is certainty. If I have pocket AA, KK, QQ; I'm certain something is going to happen, could be good, could be bad,
odds leaning in my favor, I'm going to make a major move.
If you only play the numbers, odds, etc. you will second guess yourself into paralysis; nothing is certain, until after the river.
MTT, get QJo, I decide to shove. Not the cards to shove on, but sometimes you have to defy the odds early in tournie, to get your chip stack going.
QJo ahove didn't work out, but at least I'll sleep easy. At least in the "we took a chance" loser's lounge, there isn't poker anxiety; they went for it, lost, shoulder shrug; maybe next time.
