I think the memetic nature of humans is so strong across investing, but also other areas of life. There's a phrase in poker which is called playing on tilt. You do have to learn to master your mind. i did walk away with a better mastery of my mind as it related to making bets and speculating,. building my own conviction, knowing my own rules. But on too many days i was playing on tilt... And playing on tilt is a bad strategy. We will not just reflect on our own strategy. We are influenced by other people's actions in making these decisions.
