Why want for money when basic needs are met? If trading in a simulator, why does it still hurt when wrong? Why is there stress when nothing is on the line? When you do not know the answers to these questions, fear will be your companion. A loss can mean you feel worth-less.
If you go beyond the money as a measure of your worth, a loss can mean a mistake was made, or be normal part of your operations. A win can hide a mistake or be part of normal operations.
When going beyond the money and learning how to lose, a new measure can emerge. The measurement of trading behavior. Instead of looking at daily, weekly or monthly PnL, consider what happened when at the limits of the trading or risk management plan. Was execution of the actions in line with the plan or not? If it was, it was successful, if not, there is more training to do. Let trading behavior be the measure of success or failure. Let each approach of the limits be a learning oportunity to see how you hold up. While many aren't cut out for short term trading, they don't have an edge, they don't have to lose due to reckless decisions. Let trading behavior be the measure of success and results will be inline with expected returns from the predefined risk management and trading plan.
