A lot of my work deals with this emotion of discouragement or fear, and this emotion cannot be approached without humor because then things become indigestible. You don't want to eat them; you don't want to be in contact with them.
An optimist is a person who sees only the lights in the picture, whereas a pessimist sees only the shadows. An idealist, however, is one who sees the light and the shadows, but in addition sees something else: the possibility of changing the picture, of making the lights prevail over the shadows.
