It turns out that the process of working toward a goal, participating in a valued and challenging activity, is as important to well-being as its attainment.

I use the term happiness to refer to the experience of joy, contentment, or positive well-being, combined with a sense that one's life is good, meaningful, and worthwhile.

Exercise may very well be the most effective instant happiness booster of all activities.

No one in our society needs to be told that exercise is good for us. Whether you are overweight or have a chronic illness or are a slim couch potato, you've probably heard or read this dictum countless times throughout your life. But has anyone told you-indeed, guaranteed you-that regular physical activity will make you happier? I swear by it.

Find a happy person, and you will find a project.

I prefer to think of the creation or construction of happiness, because research shows that it's in our power to fashion it for ourselves.

People prone to joyful anticipation, skilled at obtaining pleasure from looking forward and imagining future happy events, are especially likely to be optimistic and to experience intense emotions.
