One should not become an artist because he can, but because he must. It is only for those who would be miserable without it.
There are neither good nor evil, only the existence and action.
An artist would not rise above the mediocrity if he condemns it.
To try to understand another human being, to grapple for his ultimate depths, that is the most dangerous of human endeavors.
An artist without ideas is a mendicant; barren, he goes begging among the hours.
You cannot be the good all the time — sometimes it is necessary to get angry. [Vincent Van Gogh]
