“Our leader has a vision.”
and
“Our leader has vision.”

The latter is the context I was using, which I believe is synonymous with “Our leader has imagination.” It takes imagination to create a vision. Therefore, to become a leader, one must develop and train and exercise their imagination so they are capable of developing a vision. I left vision out of my list because I was writing about how to develop leadership capability rather than how to recognize leaders.

I agree that a leader cannot lead without a vision. I also agree what you said about true leadership being positive concept. That is why I stand by my position that character is more important than vision. Without good character the person is not worth following, probably has a vision that is also not worth following and therefore is not really a leader at all.

That’s my clarification. I appreciate your thoughts and the challenge to my position. You have inspired me to write a sequel to this post.

While I agree with most of the leadership ingredients that you have listed. I find one ingredient- what I purport to be the most fundamental ingredient suspiciously missing. Vision. While imagination helps in the creation and articulation of vision, it, in and of itself is not vision.
IMHO vision is the first ingredient. Without it, how do I know where to lead?
Also, by your ingredients, I can only assume that you only refer to leaders that we would all agree are positive. Because if you match these ingredients against some of the greatest (not so positive) leaders you will find key ingredients missing. Perhaps, it would be an interesting excercise to isolate the missing ingredient in (bad) leaders.
