I'm trying to broaden the scope of positive psychology well beyond the smiley face. Happiness is just one-fifth of what human beings choose to do.

We don't function well as human beings when we're in isolation.

Remember that we are all human beings trying to do what we love to do.

This has suggested to some that the very structure of human thought is oppositional-that is to say, rational and associative, rather than linear and categorical.

When it comes to the pinch, human beings are heroic.

Human beings have always been mythmakers.
