Yes, it is profitable to make us more motivated. But, all traders must make mistakes. However, the error factor will also be a good motivator for not repeating mistakes. We take lessons from mistakes to improve quality. and Sometimes I make a mistake by entering one more 0 or whatever number at the last price to place an order and it helps me to avoid losses but I have never made a profit buying mistakes. Whenever I can avoid the opportunity to lose, I feel very happy and I know that luck is not always there to help me as it is now.
