I decided to sell my drawings. However, I didn't want people to buy my drawings because the professor of physics isn't supposed to be able to draw - isn't that wonderful - so I made up a false name.

I knew I belonged to the public and to the world, not because I was talented or even beautiful, but because I had never belonged to anything or anyone else.

Many are they who have a taste and love for drawing, but no talent; and this will be discernible in boys who are not diligent and never finish their drawings with shading.

Man, alone, has the power to transform his thoughts into physical reality; man, alone, can dream and make his dreams come true.

Man is the only creature that refuses to be what he is.
