Peace of mind should not be an objective of life.  More often than not, peace of mind leads to a state of peace without mind.  There are causes that should call us; there are cries of help that should move us; there are people who need us; there are conditions that demand us.  Floating around in one’s own tub of butter should not be a goal for an intelligent life.  Let us find tranquility in the doing, not in the being.
