I often think that the night is more alive and more richly colored than the day.
I put my heart and my soul into my work, and have lost my mind in the process.

Do not quench your inspiration and your imagination; do not become the slave of your model.

But I always think that the best way to know God is to love many things.
A good picture is equivalent to a good deed.
If one is master of one thing and understands one thing well, one has at the same time, insight into and understanding of many things.
