Many people seem to think it foolish, even superstitious, to believe that the world could still change for the better. And it is true that in winter it is sometimes so bitingly cold that one is tempted to say, 'What do I care if there is a summer; its warmth is no help to me now.' Yes, evil often seems to surpass good. But then, in spite of us, and without our permission, there comes at last an end to the bitter frosts. One morning the wind turns, and there is a thaw. And so I must still have hope.
Vincent Van GoghBut 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.
