Previously, I had moments when I lost money in things that I didn’t understand, for example, such as trading.
I am very grateful to such realizations, because after that I stopped engaging in activities that I did not understand well, because the risks were incommensurable. Now I'm not running away because losing is part of the game.
You should really realize or anticipate that losses are normal but since you are dealing with investment then you should try your best on minimizing the risk as small as possible.
When you do anticipate that much that you can make money and when losses do hits or strikes you then that would end up on frustration and stress and thats the time
you would really be having those kind of feelings on where you are down and afraid to deal with the market again but honestly, self realizations from your mistakes
which makes you a better or improved person because you wont really improved out if you do let yourself shackled with your mistakes and afraid to face it off.
