Happiness is not out there for us to find. The reason that it's not out there is that it's inside us.

If you're not happy today, then you won't be happy tomorrow unless you take things into your own hands and take action.

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.

Forgiving people are less likely to be hateful, depressed, hostile, anxious, angry, and neurotic.

Thus the key to happiness lies not in changing our genetic makeup (which is impossible) and not in changing our circumstances (i.e., seeking wealth or attractiveness or better colleagues, which is usually impractical), but in our daily intentional activities.

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

...The more a person is inclined to gratitude, the less likely he or she is to be depressed, anxious, lonely, envious, or neurotic.
