Like i always say they can be Managers but, they are not true leaders
1.Leaders create a vision, managers create goals
2.Leaders are change agents, managers maintain the status quo
3.Leaders are unique, managers copy
4.Leaders take risks, managers control risk
5.Leaders are in it for the long haul, managers think short-term
6.Leaders grow personally, managers rely on existing, proven skills
7.Leaders build relationships, managers build systems and processes

Etc..............
