My favorite (life) quote - so I do agree with what Mike Matusow said here (that poker is a mindset and if you get negative, you can't win), considering how 'weird' the Mouth is behaving nowadays, on and off the poker tables, is rare to agree with him on anything
PS. That's also why I've worked a lot on my mental
poker game in the past few years and why I keep recommending on our community
The Mental Game of Poker 1&2 by Jared Tendler... IMO this is an aspect of the game overlooked by many (good) poker players and it has a direct effect on their success on both short and long term...
