This piece on Winston Churchill illustrates (with some humor) the importance of clarity in leadership. Certainly the circumstances of war contributed to Churchill’s clear messages, but urgency is often summoned from within…regardless of the circumstances.
Another interesting reality about Churchill was that he knew he didn’t have time to waste. Having Hitler breathing down your neck will do that. The attitude that prevails today is contrary to Churchill and his time. We feel that we do have time.
If you’re planning on leading anyone or any organization to greatness, you must act swiftly. Know what you want and pursue the "end."
