Because of their positions, all leaders know stuff that others in the organization do not know. Thus the need for professional confidentiality.
I recently had to correct a colleague who inadvertently leaked some confidential info during a meeting. He responded to my correction by saying, "You're right, I should not have said that. I don't get corrected very often, but I need it. Thanks."
He not only admitted his mistake, he embraced correction and he thanked me for it. I am thankful I get to work with such humble and wise people all over the world.
How do you respond to correction? Do you accept correction, or get offended? Do you love correction, or do you hate it?
A long time ago a really wise man wrote: "he who hates correction is stupid." (Proverbs 12:1) Sadly, that verse describes many leaders today.
Wanna be a smart leader? Make peace with the fact that you are often wrong and need correction, then surround yourself with people who are willing to "speak the truth in love."
