The best manager that I ever had was able to motivate by providing coaching which obviously led to more opportunities. She was also a fantastic team leader. We were on a sales team and every morning we had sales meetings prior to our regular workday starting where we went over our goals and expectations for the day and everything was done in a very positive manner. That was really the best way that I found that a manager could motivate a team is by remaining positive and providing constructive feedback and coaching.
