You are overly fixated on that one or two losses; essentially, you are not reviewing your strategy, but judging yourself. After losing one or two trades, you lie in bed tossing and turning unable to sleep. "If only I hadn't entered at that time." "If only I had exited sooner." Once such thoughts pop up, they just won't stop. But have you considered whether this trade was done according to the rules? If it was, then that money was meant to be lost. Just like paying rent for a store, doing business has its costs. If it wasn't, then you should reflect. But once you've reflected, that's it; don't keep judging yourself over and over. Many people, after a loss, translate "loss" into "I'm not good enough." The correct way to deal with losses is that they do not negate your worth.
