Don't Waste Time Coaching People...

...unless they ask for it.

Seriously. How many times have you tried to convince someone their idea was wrong when they didn't ask for advice? I'm guessing that nearly 100% of the time they didn't take your advice.

Roy Williams quotes a friend as saying "Unsolicited advice is abuse."

Help the people who want and ask for your expert advice. Spend your time there. Everything else is wasting your time.
