Work at the same time on sky, water, branches, ground, keeping everything going on an equal basis... Don't be afraid of putting on colour... Paint generously and unhesitatingly, for it is best not to lose the first impression.

Don't be afraid in nature: one must be bold, at the risk of having been deceived and making mistakes.

Paint the essential character of things.

But as I see it, the most corrupt art is the sentimental the art of orange blossoms which make pale women swoon.

I sometimes have a horrible fear of turning up a canvas of mine. I'm always afraid of finding a monster in place of the precious jewels I thought I had put there!

Watercolour is not especially difficult, but I must warn you to steer clear of those pretty English watercolourists, so skilful and alas so weak, and so often too truthful.

Cover the canvas at the first go, then work at it until you see nothing more to add.
