Put succinctly by Harrison Owen, 'leadership is not advanced management'! Get to know yourself in your Leader Mode – it's way different to you as Operator/Manager:
Most professional development is based on the notion that successful people acquire new role-appropriate skills as they move up the hierarchy. But making the transition from manager to leader requires subtraction as well as addition: To make room for new competencies, managers must rely less on their older, well-honed skills. To do so, they must change their perspective on how to add value and what to contribute. Eventually, they must also transform how they think and who they are. Companies that help their top talent reinvent themselves will better prepare them for a successful leadership transition.

Your ability to manage is measured by what you know and what you get done, but your ability to lead is measured not only by your competence but also by your ability to communicate who you are and what you stand for.

When you're in your Leader Mode, you'll be as Ghoshal and Bruch describe:
The truly effective leaders we've observed are purposeful, trust in their own judgment, and adopt long-term, big-picture views to fulfill personal goals that tally with those of the organization as a whole.
I think that what is missing is a profound sense of the depth of the matter. Leadership is often spoken of as if it were simply advanced management. The presumption is that whatever the manager is supposed to do, the leader does more of and better. Leadership is not advanced management; in fact, it is radically different from management, and to equate or confuse the two is to miss an essential distinction, and that distinction, if observed, can take us to the heart of the matter.
The tasks of management and leadership are, I believe, separate and distinct. To manage is to control; to lead is to work in the depths beneath the system, in the primal areas where the Dragon lives.
