" One must have a reason to "be happy." Once the reason is found, however, one becomes happy automatically. As we see, a human being is not one in pursuit of happiness but rather in search of a reason to become happy, last but not least, through actualizing the potential meaning inherent and dormant in a given situation.

This need for a reason is similar in another specifically human phenomenon - laughter. If you want anyone to laugh you have to provide him with a reason, e.g., you have to tell him a joke. In no way is it possible to evoke real laughter by urging him, or having him urge himself to laugh. "
