It is not the being seen of men that is wrong, but doing these things for the purpose of being seen of men. The problem with the hypocrite is his motivation. He does not want to be holy; he only wants to seem to be holy. He is more concerned with his reputation for righteousness than about actually becoming righteous. The approbation of men matters more to him than the approval of God.
I can't be a hypocrite as a coach because as a player that's what I wanted. I wanted feedback, I wanted communication from the boss. I showed up for work, you can yell at me if you want, but I want input. So that's the kind of coach I want to be.
It is necessary that the prince should know how to color his nature well, and how to be a hypocrite and dissembler. For men are so simple, and yield so much to immediate necessity, that the deceiver will never lack dupes.
