There is no wealth but life. Life, including all its powers of love, of joy, and of admiration. That country is the richest which nourishes the greatest numbers of noble and happy human beings; that man is richest, who, having perfected the functions of his own life to the utmost, has also the widest helpful influence, both personal, and by means of his possessions, over the lives of others.
John Ruskin
The men and women who have the right ideals . . . are those who have the courage to strive for the happiness which comes only with labor and effort and self-sacrifice, and those whose joy in life springs in part from power of work and sense of duty.
Theodore Roosevelt
