Hi John,
So many of us who do this work have broken our arms, bruised our knees, blackened both eyes metaphorically speaking.  As you said, culture change is disruptive.  It becomes a contact sport, just no tackles.  You do a good job explaining just how culture change is a contact sport.  And since we're running with the sports themes, the patience you advocate is key to winning the game. You run plays, see how it goes, and readjust as needed. Changing the context in which people do their work is no different.

Thanks, John, for keeping this important topic in our conversations.
Shawn
