The Psychology of Money

When things are going extremely well, realize it’s not as good as you think. You are not invincible, and if you acknowledge that luck brought you success then you have to believe in luck’s cousin, risk, which can turn your story around just as quickly.

Don’t get too attached to anything—your reputation, your accomplishments or any of it. I think about it now, what does it matter? O.K., this thing unjustly destroyed my reputation. That’s only troubling if I am so attached to my reputation.

But most of the time today is not that important. Over the course of your lifetime as an investor the decisions that you make today or tomorrow or next week will not matter nearly as much as what you do during the small number of days—likely 1% of the time or less—when everyone else around you is going crazy.

Studying history makes you feel like you understand something. But until you’ve lived through it and personally felt its consequences,

But every financial decision a person makes, makes sense to them in that moment and checks the boxes they need to check. They tell themselves a story about what they’re doing and why they’re doing it, and that story has been shaped by their own unique experiences.
