Laughter

Well, this too-good-to-be-true fact, is not far-fetched compared to what we have in our world today. A lot of persons barely laugh a day; they are enveloped in the busyness and challenges inherent in their environment, and failing to recognize that their happiness is their responsibility and of course, a choice-- that they must consciously make every day of their lives.

When one allows his or her physical environment to be the major determinant of his or her happiness, such a person is must likely to be hurting; because there's no perfect environment.

You'll have to create your happiness, and laughter can be a sure tool.
