if you learn from your own mistake , you will spend time and money too .
better to learn from other's mistakes .
if your query is related to crypto , then be wise while taking decision of delling and buying , FOMO and panic sell may cause you loss .
The reason why a lot of people are doing very well in their fields today is because of their experiences which they were able to garner from their mistakes. We cannot do without going wrong some times as no one is perfect but what is necessary is to make use of those wrongs to get a better part of ourselves. A lot of people instead of that always end up getting down cast which is pretty bad.
Running from failure is not even a good thing because sometimes it just happens and the idea is to learn from it upfront, get better and then be able to make great decisions in the long run. It is important to always know that you can go wrong, but the interesting part of it is that there is always an opportunity to retrace and make the best use of it. Once you take it as part of life, you will always get the benefit of even failing.
I believe that it's preposterous to enter the cryptoworld without a strategy that has a positive expectancy. It can be a simple HODL or cutting losses quickly but it ought to be chosen beforehand. Pursuing a strategy should prevent you from becoming emotionally and financially devastating
