"And I urge you to please notice when you are happy, and exclaim or murmur or think at some point, 'if this isn't nice, I don't know what is.'" -- Kurt Vonnegut
"Happiness is like a butterfly; the more you chase it, the more it will elude you, but if you turn your attention to other things, it will come and sit softly on your shoulder." --Henry David Thoreau
