Key to success

“I whistle while I work and scarcely notice it. I laugh because I am happy. It sets the rhythm of my soul. I am glad to be alive and to learn so many fascinating things about our incredible world. I am happy to feel the pulses of my heart and the musings of my mind. I am happy because there is so much fun and joy in the miracle of life.” – Robert Muller, former assistant secretary-general of the UN, in Most of All They Taught Me Happiness, page 95, Doubleday, 1978
