From The Psychology of Money: Timeless Lessons on Wealth, Greed, and Happiness by Morgan Housel:
At a party given by a billionaire on Shelter Island, Kurt Vonnegut informs his pal, Joseph Heller, that their host, a hedge fund manager, had made more money in a single day than Heller had earned from his wildly popular novel Catch- 22 over its whole history. Heller responds, “Yes, but I have something he will never have … enough.”
The idea of having “enough” might look like conservatism, leaving opportunity and potential on the table.
I don’t think that’s right.
“Enough” is realizing that the opposite—an insatiable appetite for more—will push you to the point of regret.
The only way to know how much food you can eat is to eat until you’re sick. Few try this because vomiting hurts more than any meal is good. For some reason the same logic doesn’t translate to business and investing, and many will only stop reaching for more when they break and are forced to. This can be as innocent as burning out at work or a risky investment allocation you can’t maintain.
