Remember the first trading lesson you learned as a newbie? Did it come from a win or a loss? A loss teaches you about the reality of the market, protects you from becoming cocky, and humbles you. When you are a beginner trader, a small loss is not a terrible thing. Losses teach you proper trading risk management strategies and techniques and respect for the market and prepare you for long-term success.

Our learning is from the loss experienced, because if we experience loss we cannot easily forget it and the next time that we face the same situation a situation that make us loss then we can make or try another strategy to avoid losing again, so for me it is our loss who make us more knowledgeable and become a better trader in the future.
It's true that basically losses will make us sad, but on the other hand, if we want to change the mindset, losses make us learn,
mourning losses without doing anything I don't think it's a wise thing,
the more experience, our knowledge also increases and that's good for sure.
