Poker is the most important practice

Forget about all those mindfulness and positive thinking and ying yang mumbo jumbo. 50% of your problems is due to other people. The only way to solve the problems is using poker game theory thinking.

When you deal with difficult people, there is a lot of times you need to play the chicken game, see who back down first. You need to be willing to take risk and not afraid of losing. Only then people would not bully you. Most of the time the cost of both sides losing the chicken game is much less than the psychological cost of backing down from the chicken game where the bully continue bullying you long term.

Another poker skill that can be applied to life is detach from your emotion. Dont need to detach from thinking, all else you gonna think? Detach from your emotion and let thinking continue.

You need courage to fight with other people. Strong muscles builds up courage. Thus you need to learn karate or do weight lifting. If you practice only weight lifting, it would be deadlift, totally addictive.
