It stems from an amazing quote in Matthew Mcconaughey's book Greenlights. I highly recommend reading it if you haven't already! He gets himself into a situation where he has to wrestle the best warrior in a South American village, and is terrified of losing. After the fight a woman tells him that he gained the village's respect the moment he accepted the challenge. She says "It's not about win or lose, it is about do you accept the challenge"

This has always inspired me so much! Thanks for reading :)
