…happiness is not a matter of fact but of attitude. If one is unhappy, he finds the facts to substantiate his unhappiness; if happy, the facts to support his happiness.

Happiness, while independent of facts as a cause, can itself become a fact. We all can recognize the fact of a happy man or woman. Occasionally such a recognition of fact can even trigger a spontaneous change of attitude. This is the effect that an example can have on us. He has not proved the efficacy of his view by logic; rather, by example, he has demonstrated it.
