A little Firehouse Zen humor, borrowed from the prolific author, Anonymous: "Rome did not create a great empire by having meetings, they did it by killing all those who opposed them."
I actually do have a sense of humor, although it tends to be on the dark and dry side. It helps to have a sense of humor about life in general, and especially in leading and in implementing change because frankly, none of this stuff ever goes smoothly. And if it does, you can be reassured that someone is hiding something for an unwelcome surprise later.
At the heart of every successful leader is a light heart at the appropriate moments. But as is with everything in leadership, timing and opportunity must be right. Failure to observe that dictum can be fatal to your career and your reputation.
By the way, I know Anonymous isn't an author. He's a spokesman for the Defense Department..
