There was a trader I knew who refused to look at a position once he closed it. Never checked if he sold too early. Never checked if it ran higher the next day. Never regretted a dime.
I asked him why he never looked back.
He said, “Rearview mirrors cause crashes. I drive forward.”
Years later, he became one of the most consistent, stress-free traders I’d ever seen. Not the richest — but the calmest. And calm traders last longer than rich ones.
Lesson: Your past trades are ghosts. Let them stay dead. Regret is a tax that compounds faster than any return.
