the hardest arithmetic to master is that which enables us to count our blessings.

世界上最難的算術(shù)題是如何清點我們的祝福。

according to legend, a young man while roaming the desert came across a spring of delicious crystal-clear water. the water was so sweet, he filled his leather canteen so he could bring some back to a tribal elder who had been his teacher.

據(jù)傳說，一個年輕的男子在漫游沙漠途中看到一泉如水晶般清澈而可口的水。水的味道非常甜美，于是他灌滿了他的皮水壺，這樣就可以帶一些回去，送給曾經(jīng)是他老師的部落長老。

after a four-day journey he presented the water to the old man who took a deep drink, smiled warmly and thanked his student lavishly for the sweet water. the young man returned to his village with a happy heart.

經(jīng)過四天的旅程，他把水呈獻給老人。老人深飲一口，和藹地笑了笑，并深切感激學(xué)生贈予他甜美的水。年輕人懷著愉快的心情回到了村莊。
