Classical Composer Franz Joseph Haydn (1732–1809) said:

Often when I was wrestling with obstacles of every kind, when my physical and mental strength alike were running low and it was hard for me to persevere in the path on which I had set my feet, a secret feeling within me whispered: 'There are so few happy and contented people here below. Sorrow and anxiety pursue them everywhere. Perhaps your work may, some day, become a spring from which the careworn may draw a few moments rest and refreshment.
