Exactly poker is a long grind. You need patience, discipline, and the right mindset to handle swings and keep improving.I totally agree to that and whats really important to understand: This game tests the obove abilities to an ultimate lvl and you have to treat it as a marathon. You wont stand the test of time without being satisfied and at peace with your own approach. Nowadays if you really want to get something out of this game (perhaps a living) you need that never-give-up mentality and the necessary killer instinct. Otherwise, it overwhelmes most players.
