Context: I do not believe that sheer suffering teaches. If suffering alone taught, all the world would be wise, since everyone suffers. To suffering must be added mourning, understanding, patience, love, openness and the willingness to remain vulnerable. All these and other factors combined, if the circumstances are right, can teach and can lead to rebirth.

Creo que son los males del alma, el alma. Porque el alma que se cura de sus males, muere.
Voces (1943)

Letter from Naples, Italy to Otto Grautoff (1896); as quoted in A Gorgon's Mask: The Mother in Thomas Mann's Fiction (2005) by Lewis A. Lawson, p. 34
Context: I think of my suffering, of the problem of my suffering. What am I suffering from? From knowledge — is it going to destroy me? What am I suffering from? From sexuality — is it going to destroy me? How I hate it, this knowledge which forces even art to join it! How I hate it, this sensuality, which claims everything fine and good is its consequence and effect. Alas, it is the poison that lurks in everything fine and good! — How am I to free myself of knowledge? By religion? How am I to free myself of sexuality? By eating rice?

As quoted in "10 questions for Lance Armstrong" by Bill Saporito in TIME magazine (28 September 2003) http://www.time.com/time/magazine/article/0,9171,1005777,00.html
Context: I'm not happy if I'm not doing some physical suffering, like going out on a bike ride or running. First, it's good for you. No. 2, it sort of clears my mind on a daily basis. And it's a job. My job is to suffer. I make the suffering in training hard so that the races are not full of suffering.

Variant: I suffer migraines. I do not suffer fools.
