Roy Cooke has an article on narcissism and poker in the March 7 issue of Card Player magazine:
Do you play as well as your opponents, yet get much poorer results? If so, you probably focus too much on the times you're unlucky and forget the lucky times.
Do you blame bad luck for your disappointing results? Blaming bad luck is just plain stupid. Cards are random, and over the long term, you'll have approximately the same luck as everyone else.
Do you blame opponents' mistakes? Your opponents' bad play is not causing you to lose. It's just another way of avoiding responsibility.
Do you openly criticize other players? Narcissistic thinking causes you to put down other players as a means of elevating your own self-image.
Do you keep accurate records of your results? If not, ... you may not want to . . because you don't want to know the truth.
Do you study the poker literature? If not, you're almost certainly narcissistic because you think you already know more than the poker authorities. Nearly every top pro studies because they know that nobody knows it all.
Do you have a "poker buddy?" If you don't have one, you're indirectly saying that you don't want constructive criticism. We need another pair of eyes to examine our play and plug our leaks.
