The habit of viewing life as a whole is an essential part both of wisdom and of true morality, and is one of the things which ought to be encouraged in education. Consistent purpose is not enough to make life happy, but it is an almost indispensable condition of a happy life. And consistent purpose embodies itself mainly in work.

Bertrand Russell (1872-1970) English mathematician and philosopher

Conquest of Happiness, Part 2, ch. 14 “Work” (1930)
