Back of every mistaken venture and defeat is the laughter of wisdom, if you listen. We go forward by failure. Every blunder behind us is giving a cheer for us and only those who are willing to fail shall taste the dangers and splendors of life. To be a good loser is to learn how to win. The real coward is he who sees no glory in failure.

Carl Sandburg (1878-1967) American poet, biographer

Incidentals (1904)
