I’ve forgotten the exact quote, but Marcus Aurelius wrote that no one can see inside your head so you might as well walk around and think amazing, incredible, noble things – because no one will ever know that you aren’t thinking the same as they’re thinking. It’s your mind, after all. You can think whatever you want.
“What lies behind you and what lies ahead of you
are small matters compared to what lies within you.”Ralph Waldo Emerson
