I've seen this play out a lot for me, wholly agree! GREAT POINT! That has to BE THEE ONLY WAY or else how could they play nose bleed stakes thinking Ooops there goes the house, there goes the Ferrari lol but easier said than done!If you are nervous when you play than you have already lost. A key aspect, in my opinion, is having a detachment to the money that is in play. If you are not able to make the correct move due to fear of losing or playing above your means then it is going to be an issue in the long term and most likely in the short term as well.
I do not get nervous, maybe a bit tense on some decisions.Sometimes I want to smash the monitor in anger. I understand that the nerves interfere with the game but I can not help myself.
