Who you are as a person began before you ever thought of trading and who you will be as a person will extend beyond your trading. When personal self-worth entwines with trading, it not only damages self esteem, it sabotages the trading. You hear about it. You read about it. Don't be misled.
Traders tell stories.
They write stories. They tell how great they are. And sooner or later, big downfalls. It goes with the territory. Consider the outsized egos of certain traders who brought themselves and those associated with them to ruin.
