I think one of the most important skills you can have in poker is being really good at changing your mind. Poker players spend so much time trying to be right. We debate hands, defend our lines, argue about strategies and sometimes attach way too much of our ego to whether our original opinion was correct. But I think the best players I've been around are almost the opposite. They can passionately believe something on Monday, see better evidence on Tuesday and by Wednesday they've completely abandoned the idea. No ego. No trying to justify why they were kind of right. No moving the goalposts. Just "yeah, I was wrong." I think that's an incredibly powerful skill. Poker changes so quickly and there's so much information that it's almost impossible for everything you believe today to still be correct in a few years. I've had strategies that I was absolutely convinced were good, probably taught them to other people with huge conviction, and then six months later realised I was completely wrong. I don't think that's embarrassing. I actually think being able to do that is one of the reasons I've managed to keep improving. The dangerous player isn't the one who gets things wrong. Everybody gets things wrong. The dangerous player is the one who needs to keep being right after the evidence has changed. Your job isn't to defend the player you were yesterday. Your job is to make the player you are tomorrow better. So have conviction in what you believe. Argue your side. Try to prove it. Challenge other people's ideas. But when somebody shows you something better, don't fight to protect your old opinion. Steal theirs. Being wrong for one day costs you nothing. Being too stubborn to change your mind can cost you years.
