Actually, there's no part of forgetting your losses most of them are the teachers, and become most likely a core memory. Every mistake we've made on that part will become a lesson to us so we can avoid making the same mistakes again but of course depends on the person if they will take this as a serious matter because even though we lose a lot of times but we commit with the same problem we are just waiting our money and effort from getting nothing.
Not every loss teaches you something there are many similar types of losses that just happen, and there’s no way to avoid them. But I think such losses are even easier to forget. That’s why there’s no need to try to learn a lesson from every single defeat, these kinds of losses have happened and will continue to happen. Our task is simply to make sure there are as few of them as possible. And the main goal is to calculate the bet in such a way that these losses don’t affect you financially or emotionally.
