I think I have always been able to communicate good ideas to others and then carry through. Ultimately everyone understood the direction, the mission and their role and after time the entire team saw the same problem solutions. Great leaders tend to be great dreamers - painters of a picture. They have a vision that is never quite fulfilled. A leader can never be satisfied with where you are.
Most people dream small dreams.
You have to dream big dreams. I have always dreamt big dreams. I'm not sure that I agree that I was a leader who took charge in all decisions. I can name on one-hand situations where I mandated a decision. What I did was made sure everyone in each department understood the perspective of another department before they made a decision.
