Over the years, my concentration improves.
I've been playing poker since late 2018, as time goes by my concentration improves and I find myself getting less tired after playing for many hours straight.
When I started playing after 5 or 6 hours and I used to play any game because I was very tired and today I have a lot more patience. the mental part of poker is one of the most important foundations in my opinion for the player to evolve his game, I believe that the mental part overlaps the theoretical part of the game, a player with a very good mental part has an advantage in my opinion.
I see these great poker players, and it calls me very much attention the fact that they never or almost never get out of control even playing high stakes, many players know the theory of poker but it takes a very strong mental part to never get out of this theory, yeah that's what makes an above average player, in my opinion.
