" 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[....]

Everyone has his own specific vocation or mission in life

to carry out a concrete assignment which demands fulfillment.

Therein he cannot be replaced, nor can his life be

repeated. Thus, everyone's task is as unique as is his

specific opportunity to implement it."
