I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.
To become truly immortal, a work of art must escape all human limits: logic and commonsense will only interfere. But once these barriers are broken, it will enter the realms of childhood visions and dreams.
Every child is an artist. The problem is how to remain an artist once we grow up.
