The secret of genius is to suffer no fiction to exist for us; to realize all that we know; in the high refinement of modern life,in arts, in sciences, in books, in men, to exact good faith, reality, and a purpose; and first, last, midst, and without end, to honor every truth by use.
When you start working, everybody is in your studio- the past, your friends, enemies, the art world, and above all, your own ideas- all are there. But as you continue painting, they start leaving, one by one, and you are left completely alone. Then, if you are lucky, even you leave.
