Good poker players need to have an edge to win. What differs a good poker player from a bad one? A bad poker player does not expect to win, while a good poker player does. Why? The bad player hopes he gets lucky and the professional relies on his skills!
A good poker player understands that different games require different kinds of discipline.
For example, a disciplined no-limit player can be a bad limit player. He or she does not play too many hands, but only the good ones, which also have a chance to win.
The main difference between a disciplined no-limit and fixed-limit player is that the fixed limit player takes care not to lose his money slowly and bit by bit, while the no-limit player has to take care not to lose his whole money with one hand.
A good poker player knows when he should play and when to stop. He recognizes when he doesn’t play good and when he lacks discipline. That’s the moment when a good poker player calls it a day.
A good player knows that he is not perfect and that he makes mistakes. If he makes a mistake, he learns from it and doesn’t begin to cry or blame others for it. It’s not bad to commit an error. It’s just bad commit a mistake twice.
