No living creature can laugh except man. Trees may bleed when they are wounded, and beasts in the field will cry in pain and hunger, yet only I have the gift of laughter and it is mine to use whenever I choose. Henceforth I will cultivate the habit of laughter.

　　I will smile and my digestion will improve; I will chuckle and my burdens will be lightened; I will laugh and my life will be lengthened for this is the great secret of long life and now it is mine.

　　I will paint this day with laughter; I will frame this night in song. Never will I labor to be happy; rather will I remain too busy to be sad. I will enjoy today's happiness today. It is not grain to be stored in a box. It is not wine to be saved in a jar. It cannot be saved for the morrow. It must be sown and reaped on the same day and this I will do, henceforth.

　　And with my laughter all things will be reduced to their proper size. I will laugh at my failures and they will vanish in clouds of new dreams; I will laugh at my successes and they will shrink to their true value. I will laugh at evil and it will die untasted; I will laugh at goodness and it will thrive and abound. Each day will be triumphant only when my smiles bring forth smiles from others and this l do in selfishness, for those on whom l flown are those who purchase not my goods.

　　只有人类才会笑。树木受伤时也会流"血"，禽兽也会因痛苦和饥饿而哭嚎哀鸣，然而，只有我才具备笑的天赋，可以随时开怀大笑。从今往后，我要培养笑的习惯。

　　笑有助于消化，笑能减轻压力，笑，是长寿的秘方。现在我终于掌握了它。

　　我要用笑声点缀今天，我要用歌声照亮黑夜。我不再苦苦寻觅快乐，我要在繁忙的工作中忘记悲伤。我要享受今天的快乐，它不像粮食可以贮藏，更不似美酒越陈越香

　　笑声中，一切都显露本色。我笑自己的失败，它们将化为梦的云彩；我笑自己的成功，它们回复本来面目；我笑邪恶，它们远我而去；我笑善良，它们发扬光大。我要用我的笑容感染别人，虽然我的目的自私，但这确是成功之道，因为皱起的眉头会让顾客弃我而去。 。我不是为将来而活。今天播种今天收获。
