"The servant-leader is servant first. It begins with the natural feeling that one wants to serve. The conscious choice begins one to aspire to lead."

"Do those served grow as persons; do they, while being served, become healthier, wiser, freer, more autonomous, more likely themselves -- to become servants?”
