How we can be happy

The first step, however, is to make a conscious choice to boost your happiness. In his book, The Conquest of Happiness, published in 1930, the philosopher Bertrand Russell had this to say: "Happiness is not, except in very rare cases, something that drops into the mouth, like a ripe fruit. ... Happiness must be, for most men and women, an achievement rather than a gift of the gods, and in this achievement, effort, both inward and outward, must play a great part."

Today, psychologists who study happiness heartily agree. The intention to be happy is the first of The 9 Choices of Happy People listed by authors Rick Foster and Greg Hicks in their book of the same name.

"Intention is the active desire and commitment to be happy," they write. "It's the decision to consciously choose attitudes and behaviors that lead to happiness over unhappiness."
