I have a different take on this than most. I have physical damage to my brain that causes me to have an erratic psychological profile. I literally can exhibit the symptoms of several dozen mental illnesses at once. I got back into poker because I am not allowed to work a normal job and have way too much time to kill. My psychiatrist also likes that to play good poker you need discipline and controlled aggression. This means I will play tournaments and review my mental state during it after I have gotten done. If I am tilting, I stop playing, period. If I am feeling hyperactive, I stop playing. I look at how well I was doing estimates of winning when I play and see if that has decreased. If it is, I stop playing. I actually will walk away after a win and not play for a little while, because the feelings can lead to me being unobjective. Your mental state can mean a lot in everything you do. This means that you need to read more than poker books and do poker tutorials to move to the next level in your play. When I played poker full time years ago, I found that enjoying a win was as important as walking away and raising your spirits from a bad loss. I do understand taking a clinical look at poker that many do today, but that leads to people that high rollers do not want to play with. I recently won a tournament online that showed me that it is enjoyable to turn off the computer after and turn on a guilty pleasure show after. I still had bad beats during the tourney, but it was more about me focused on being in the moment than it was for me to dwell on every decision. Mental health has to be considered, so sometimes that means not seeing the felt as often as you want to. Enjoy life and poker will follow.
