Most people spend their lives waiting—waiting to get rich quickly, waiting for true love, waiting for the right moment. The result is: dopamine hits only last a few days before feeling empty again. So don't wait—start now. Do whatever makes you happy. Don't wait until you're rich, don't wait until you're in a good mood, don't wait until everything is ready, because death is random—it won't wait for you to be "ready." Tell yourself, "I'm going to enjoy myself right now, immediately."
