" It has been pointed out earlier that since man is a goal-striving being, he is functioning naturally and normally when he is oriented toward some positive goal and striving toward some desirable goal. Happiness is a symptom of normal, natural functioning, and when man is functioning as a goal-striver, he tends to feel fairly happy, regardless of circumstances. "
