Leaders, we need to take off all our masks. (That includes spiritual leaders, pastors.) Check out the Harvard Business Review blog post in which the following informative video is embedded. I don't think that Peter Fuda, the author of the blog post and narrator of this video is necessarily encouraging disclosing things that only God and you need to know about. But I do think his commendation of being one's self as a leader is important. Great food for thought and prayer here.
What was that Jesus said about, "Let your yes be yes and your no be no"? Here.
UPDATE: Reading this book years ago was a help to me.
