"Before one blames, one should always find out whether one cannot excuse. To discover little faults has been always the particularity of such brains that are a little or not at all above the average. The superior ones keep quiet or say something against the whole and the great minds transform without blaming."

Of course my moods change, but the average is serenity. I have a firm faith in art, a firm confidence in its being a powerful stream which carries a man to a harbor, though he himself must do his bit too; at all events, I think it such a great blessing when a man has found his work that I cannot count myself among the unfortunate. I mean, I may be in certain relatively great difficulties, and there may be gloomy days in my life, but I shouldn't like to be counted among the unfortunate, nor would it be correct if I were.
