Is there any difference between a manager and a leader?
I believe there is. Managers focus on getting the tasks done by their team. His/her main role is to be efficient and use the resources to get results. Leaders focus on getting the tasks done by motivating and inspiring the team. Managers mostly rely on fear, authority, pressure to get the results while leaders mostly rely on purpose, intrinsic motivation, passion to get the results.
We should strive to be leaders in our own way. It takes the same amount of effort to be a manager or a leader.
