“18–40–60, which stands for a rule I teach my patients, called the 18–40–60 rule. It says that when you are eighteen, you worry about what everyone thinks of you; when you are forty, you don’t give a damn what anyone thinks about you; and when you’re sixty, you realize no one has been thinking about you at all. People spend their days worrying and thinking about themselves, not you.”
