There is no doubt that happiness is the most precious thing in the world. Without it, life will be empty and meaningless. If you wish to know how to get happiness, you must pay attention to the following two points. 　　First, health is the secret of happiness （the key to happiness）。 Only a strong man can enjoy the pleasure of life. 　　Secondly, happiness consists in contentment. A man who is dissatisfied with his present condition is always in distress. 　　無疑的快樂是世界上最寶貴的東西。沒有它，人生將是空虛的而且毫無意義的。如果你希望知道如何獲得快樂，你須注意下面兩點(diǎn)。 　　健康是快樂的要訣。唯有身體強(qiáng)壯的人才能享受人生的樂趣。 　　快樂在于知足。一個(gè)不滿于現(xiàn)狀的人終是處在痛苦之中。
