"The ultimate signal of success is that you make yourself obsolete."

I really like this quote.

To relate it to wrestling, some of the better wrestlers that I ever coached required very little instruction during the match. No yelling or scream required. They were well prepared and knew what to do in most situations.

Some people (parents) have the misconception that the best coaches are the loudest and most dramatic in the corner. While there is a time and place for such, the best coaches shouldn't have much to say during a match.

This also applies to the practice room.

Well motivated and disciplined teams don't need constant proding and yelling from the coach.

A sign of great coaching is when the structure and work ethic remains in tact in his abscence.
