"On the first day he took me to the officer’s bathroom and told me I would be responsible for keeping it clean. 'Here’s how you clean a toilet,' he said.
"And he got down on his knees in front of the porcelain bowl, in his pressed starched spotless dress uniform, and scrubbed the toilet with his bare hands.
"To a 19 year old who has to clean toilets, something which is almost by definition the worst possible job in the world, the sight of this high ranking, 38 year old, immaculate, manicured, pampered discipline officer cleaning a toilet completely reset my attitude. If he can clean a toilet, I can clean a toilet. There’s nothing wrong with cleaning toilets. My loyalty and inspiration from that moment on were unflagging. That’s leadership."
