I would say a good leader brings results. A great leader writes a new story, it's different. Obviously a new story has to incorporate a lot of results. But a story is a chapter in the life of a company that people want to write and want to remember. ↗
A good leader is one who can tell another how to reach his or her potential; a great leader is one who can help another discover this potential for him or herself. ↗
The wicked leader is he who the people despise. The good leader is he who the people revere. The great leader is he who the people say, 'We did it ourselves.' ↗
