Why are mistakes normal?

Skill learning follows a win-stay, lose-switch model. If efforts and the context of the situation lead to positive results, people tend to repeat similar actions in the future. If efforts lead to negative results, the behavioral model is changed to an alternative model to avoid future mistakes.

Analyzing mistakes made while trading is an extremely useful process. When you regularly analyze failures, you learn from your own negative experiences, which in the future leads to better avoidance of the scenarios that led to the mistakes. It also increases the intensity of vigilance to localize the conditions that led to losses.
