Normal people do not create art.

Being mad is even pleasant. But only a madman understands that.

Savoir souffrir sans se plaindre, ça c'est la seule chose pratique, c'est la grande science, la leçon à apprendre, la solution du problème de la vie.[Knowing how to suffer without complaining is the only practical thing, it's the great science, the lesson to learn, the solution to the problem of life.]
