In his book, "Man's Search for Meaning," Austrian psychiatrist Dr. Viktor Frankl documents the profound power that a life purpose exerts over an individual under even the worst of circumstances.  Frankl, who survived the Nazi concentration camps, described how prisoners who felt they had nothing to live for succumbed, while those who perceived themselves as having a mission to complete, struggled to survive. Deprived of all external supports that might give life meaning, these survivors came to realize that, in Frankl's words, "It did not really matter what we expected of life, but rather what life expected from us."  Their sense of an inner purpose pulled them through the most horrible physical and emotional experiences so that they might make their unique contribution to the world.

Everyone has a purpose in life beyond one's immediate interests and gratifications, though that purpose frequently goes undiscovered. Many people devote their entire lives to the pursuit of greater ease and pleasure. Those who had not found the "why" that gives meaning to existence may achieve material success, yet the real goodness of life will elude them. The true meaning of life lies in sharing our particular qualities of greatness with others.
