Management is clearly different from leadership. Leadership is primarily a high-powered, right-brain activity. It's more of an art it's based on a philosophy. You have to ask the ultimate questions of life when you're dealing with personal leadership issues.
Stephen CoveyPeople with a scarcity mentality think there is only so much in the world to go around. It's as if they see life as a pie. When another person gets a big piece, then they get less. Such people are always trying to get even, to pull others down to their level so they can get an equal or even bigger piece of the pie.
