Just slap something on it when you see a blank canvas staring at you with a sort of imbecility.

Art demands persistent work, work in spite of everything, and continuous observations. By persistent, I mean not only continuous work, but also not giving up your opinion at the bidding of such and such a person.

For myself, I declare I don't know anything about it. But the sight of the stars always makes me dream.

It's as interesting and as difficult to say a thing well as to paint it. There is the art of lines and colours, but the art of words exists too, and will never be less important.

It is not the language of painters but the language of nature which one should listen to, the feeling for the things themselves, for reality is more important than the feeling for pictures.

My sketchbook is a witness of what I am experiencing, scribbling things whenever they happen.

What is true is that I have at times earned my own crust of bread, and at other times a friend has given it to me out of the goodness of his heart. I have lived whatever way I could, for better or for worse, taking things just as they came.
