“Precisely when we think we’ve earned the right to relax our discipline is exactly when we need it most. The payoff for all our efforts? So much more temptation. So many more distractions. So many more opportunities. The only solution? Even more self-mastery! Achieving things is great. Becoming a selfish jerk because you accomplished them? Thinking you’re suddenly better or matter more than anyone else? C’mon.”

Ryan Holiday, Discipline Is Destiny (Page 292)
