“The best yardstick for our progress is not other people, but ourselves. Am I better than I was yesterday? This is the only question worth asking. As long as you go to bed at night a better practitioner than the one who woke up that morning, you have succeeded. Your worth should have nothing to do with how your progress stacks up relative to another.” ― Chris Matakas, My Mastery: Continued Education Through Jiu Jitsu
