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

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.

If we observe genuinely happy people, we shall find that they do not just sit around being contented. They make things happen. They pursue new understandings, seek new achievements, and control their thoughts and feelings. In sum, our intentional, effortful activities have a powerful effect on how happy we are, over and above the effects of our set points and the circumstances in which we find themselves. If an unhappy person wants to experience interest, enthusiasm, contentment, peace, and joy, he or she can make it happen by learning the habits of a happy person.

It is equally important to investigate wellness as it is to study misery.

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

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

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.
