“The decision to be positive is not one that disregards or belittles the sadness that exists. It is rather a conscious choice to focus on the good and to cultivate happiness--genuine happiness. Happiness is not a limited resource. And when we devote our energy and time to trivial matters, and choose to stress over things that ultimately are insignificant. From that point, we perpetuate our own sadness, and we lose sight of the things that really make us happy and rationalize our way out of doing amazing things.”
