this experience or observation of your fails is utterly irrelevant - even if you make only good decision (with positive equity) the realization of it can go south or you could get bankrupt if your money management isn't right
ask yourself... do you appreciate all your good decisions the same way you focus on the wrong ones - I bet you don't like almost everyone, myself included
what more, theoretically it's also possible (with non-zero probability) that all the outcomes that played out well for you were actually wrong decisions and︀ vice-versa 😉 - in other words humans are too focused on the history, suffer from survivorship︁ bias and tend to ignore the numbers behind it
that's why poker is the number︂ one game to play with kids... it's an ultimate simulation of life and how they︃ should think about their decisions as adults
