High-level poker also requires meta-awareness of your emotional state. Poker variance is brutal, even professionals can make the right decisions in close spots for months and still be on a bad losing streak.
If you aim to make money hand-to-hand over making the best decisions month-to-month, you’ll be miserable and likely lose.
Poker is not the only game you that requires a logical strategy with limited information and much uncertainty, (entrepreneurship comes to mind), but it is where I learned to mindfully control my emotions.
