So well said.  Thank you!
The manager works in a model of compensation that says, "Do the work your given and you will be compensated for it."  That is based on the premise that your work is merely a sacrifice.  The leader works in a model of blessing that says, "In doing your work you will become more for it."  The quest for better is first and foremost a matter of "being more," and from that then flows "doing more."  The leader then connects that back so that in the doing one becomes more, creating an upward spiral of personal growth.  For after all the real richness in being better is not in being better than the next person, but in being better than I was yesterday.
You capture this well with, "A true leader guides people to become all they are and evolve into something even more than that."
