For the meaning of life differs from man to man, from day to day and from hour to hour. What matters, therefore, is not the meaning of life in general but rather the specific meaning of a person's life at a given moment.
Viktor E. Frankl[Speaking of his experience in a concentration camp:] As we said before, any attempt to restore a man's inner strength in the camp had first to succeed in showing him some future goal...Woe to him who saw no more sense in his life, no aim, no purpose, and therefore no point in carrying on. He was soon lost.
