I love this passage from the book "Execution" though I would replace the word coaching with teaching:
Coaching is the single most important part of expanding others’ capabilities. You’ve surely heard the saying, “Give a man a fish, and you’ll feed him for a day; teach a man how to fish, and you’ll feed him for a lifetime.” That’s coaching. It’s the difference between giving orders and teaching people how to get things done. Good leaders regard every encounter as an opportunity to coach.
