What is the difference? Aren’t managing and leadership the same? No. The main difference between the two is this:

Leadership is about  influencing people to follow, while management focuses on maintaining systems and processes. 

The best way to test whether a person can lead rather than just manage is to ask him to create positive change. Managers can maintain direction, but they can’t change it. To move people in a new direction, you need influence.

Sometimes the best manager is like the little boy with the big dog, waiting to see where the dog wants to go so he can take him there.

Being the little boy does not appeal to me in any way.
