The most important thing I've learned about people who lament about how they poured out everything they had into something but still failed is that they quit when they failed and they never came close to giving it their all.
"Whoever blesses a friend early in the morning with a loud voice, he will not seem different from one who curses him." -Proverbs 27:14
"No one likes a motherf***er who wakes you up early and says, 'Hey, get your s*it on! It's time to go!" - David Goggins
