"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 a life in general but rather the specific meaning of a person's life at a given moment. To put the question in general terms would be comparable to the question posed to a chess champion: 'Tell me, Master, what is the best move in the world?"
---------- from Man's Search for Meaning, Viktor E. Frankl
