My own formula is roughly two hours alone for every hour of socializing. This isn’t antisocial. It isn’t a sign of depression. It does not call for medication. For introverts, to be alone with our thoughts is as restorative as sleeping, as nourishing as eating. Our motto: “I’m okay, you’re okay—in small doses.”
Don’t underestimate the quiet thinker for he/she is often bolder.
Two introverts, Ronald Reagan and Rosa Parks, spoke softly and carried a big stick. Big enough to change the world.
