How you react to your losing trades and investments is much more meaningful than how you react to your wins.
Everyone can and does react positively to wins, but not everyone can stay level headed and rational after a loss. Once you accept everyone loses trades and makes a bad investment now and again, a loser just becomes another data point vs. a reflection of your ability in trading or investing.
The goal shouldn’t be to have a 100% win rate, it should be learn and manage the losers enough so they don’t crush you fiscally or mentally.
