Quote from : An Understandable Religion Book

A life without an objective is much like a ship at sea with no port in mind. It drifts with the waves or storms, or with the whim of the captain. They are tempted to ask, amidst the battles of life, "Is the struggle worth-while?" That attitude lessens the joy of living. They who say that there is no purpose in life are not unhappy, but become dangerous to themselves and others, for they have no safe guide for their actions. Indeed, life has not objective save physical satisfactions, it is empty and valueless.
