By learning about my body and making small subtle changes I find out what I enjoy and what is effective. I'm always finessing: adjusting my diet and my workouts. You have to figure out which exercises are fun and interesting and stimulate your brain - or else you'll never keep at them.
Absurdity is what I like most in life and there's humor in struggling in ignorance. If you saw a man repeatedly running into a wall until he was a bloody pulp after a while it would make you laugh because it becomes absurd.
