Motivation Empire Blog

I am looking for some videos or names of motivational speakers who specialize in the topic of motivating leaders to be… well, leaders. I plan to show this video in a managers meeting at work with intent to motivate fellow employees in supervisory positions to be better leaders.

Does anyone know of any good videos for this? Or know of any speakers who are especially good on the topic of leadership?
