"There's this tyranny that people don't understand until they're a little after fifty years old.
They think that if they get that thing that they want, they're gonna get it, and they're gonna enjoy it, and it's never gonna go away, and then it does. They also think that if something bad happens to them, that they're gonna stay in a bad mood, or sad or angry or afraid forever.
Here's what you learn after fifty: nothing lasts, and it doesn't matter.
There's a thing that all biologists talk about, which is homeostasis, the tendency of every biological process to go back to its equilibrium, well, it works emotionally as well. Your anger, your sadness, your anger, your joy, those things don't last, for good and for bad, your heart is broken? It won't last.
When you figure that out, this is power, and if you harness that, every year's better than the last."
