In "Happy", Ian Smith presents a program that motivates readers to understand the behaviors and mind-sets that work and last, including: how to be optimistic; why optimism and realism are not opposites; how to get outside yourself; the importance of family and community; why involvement leads to contentment; shedding the treadmill mentality of getting and spending; tapping the power of simple pleasures; how to be, not just to do; and, why changing a scowl to a smile can have a deep impact.
