I don't know anything with certainty, but seeing the stars makes me dream.

One can never study nature too much and too hard

Keep your love of nature, for that is the true way to understand art more and more.

I am seeking, I am striving, I am in it with all my heart.

I believe it is one's duty to paint the rich and magnificent aspects of nature. We need gaiety and happiness, hope and love.

But I must work on in full calmness and serenity... The world concerns me only in so far as I feel a certain debt and duty towards it, because I have walked on the earth for thirty years, and out of gratitude want to leave some souvenir in the shape of drawings or pictures, not made to please a certain tendency in art, but to express a sincere human feeling. So this work is the aim-and through concentration upon that one idea, everything one does is simplified. Now the work goes slowly-a reason the more to lose no time.

What is drawing? It is working oneself through an invisible iron wall that seems to stand between what one feels and what one can do.
