Project Manager has to have leadership qualities to achieve success in projects. To carry on with these qualities for project management is good for project manager keeping in mind to regularly improvise and enhance these skills.
Another outlook is to inculcate these qualities in the team members down the line. Being a mentor for few of the team members is important to develop future project managers. Also if the team members touch down the inner feelings of project manager about the project, it becomes easier for all to synchronize their energies and move ahead in the same direction together.
