Last year, a co-worker shaved his head. Everyone in the office was stunned and wondered about the reason. Then I found out.
I watched him give a speech in Toastmasters about his new look. He said when he came home w shaved head, his wife & kids were stunned. He said all his life he held back doing things because of fear of failure. Shaving his head was an act of courage. It felt good to be bold.
What I took away from the speech was that it was a mid-life-crisis release of steam. He let the hair grow back.
