The attitude of always looking on the bright side of things will definitely be of inestimable benefit to us in our real life. Things seldom go one’s way. That’s a popular saying too old to warrant re-quoting. But, one will certainly meet with one setback after another on his life’s long journey.
1. Inestimable [ɪnˈestɪməbl] 不可估量；無法估量的，be of inestimable benefit to sb/sth表示使某人/某物受益很多。如劍橋詞典例句：
I believe that a national disaster fund would be of inestimable benefit to the farming industry.

第三、四、五句：每當失意時，人總覺得別人為什麼比自己幸運？別人生意興隆、仕途平坦、財源廣進、名成利就；自己為什麼如老牛破車，踽踽獨行在暮色四合的郊道上？
When frustrated, one is apt to wonder why the more fortunate can fare so well either in business or officialdom, making a pile or enjoying both fame and wealth, while he himself, like an old ox pulling a rickety cart, has to trudge all by himself on a country road thick with dusk.
1. Fare 成功（或不成功、更好等）；進展；進行，如柯林斯詞典例句：

This entire rickety structure was hanging from the limb of an enormous leafy tree.
這整個快要散架的搭建物吊掛在一棵枝繁葉茂的大樹的枝杈上。
4. Cart [kɑːrt] n.（兩輪或四輪）運貨馬車；手推車；手拉車。如柯林斯詞典例句：

第六、七句：果真如此嗎？杯中只有一半水，有人喜孜孜說：「好呀！還有半杯」， 有人愁眉苦臉：「哎呀！只剩下半杯了」，分別就在這裡。
Is that true? Now take for example a cup half filled with water. Some, in the face of it, may exclaim with delight, 「Great, the cup is half full!」 Some may grumble gloomily, 「Too bad, the cup is half empty!」 You see how the two kinds of people differ.
1. Exclaim [ɪkˈskleɪm] 呼喊；大聲說；大喊。如牛津詞典例句：
She opened her eyes and exclaimed in delight at the scene.
