Transition from Manager Mode to Leadership Level

True -- but dealing with people is the hardest thing ever, they have their own politics.

Assuming leaders have all the traits that you ascribe to them, why would they still be managers? How many of the great leaders you have known used management as a stepping stone to becoming leaders. To expect a manager to have all those leadership qualities and to remain a manager when their drive and ambition pushes them to the 'higher role' of leadership runs counter to the main thrust of your argument. If the two roles can be separated, and I am not convinced that is the case, it would be more surprising if a lot of managers are also leaders.

Poorly written article, you have not thought through the long term consequences of you argument. By your own standards you probably fail the leadership test.

True "Leadership" has nothing to do with a position. Leadership can and does happen at any level in a company or organization. You may have a guy on the loading dock who is more of a leader than the person who serves in an executive position. Leadership in it's more basic form is influence with others.

Leadership knows what and when to do something, management knows how to do something. Usually a manager is one who "tells" rather than actually "doing".

Probably the best book I've read, among probably 70 or so, is "Launching A Leadership Revolution" by Orrin Woodward and Chris Brady. It deals with the Art and Science of leadership, defining leadership, being able to measure leadership skills and effectiveness with the "Trilateral Leadership Ledger", character, task, relationship.
