There was once a farmer who devised a competition between his dog and his rabbit.一位農夫曾為他的狗和兔子組織一場比賽。

He made a hole in one of his biggest fields, and hid a carrot and a bone in it. 他在他最大的田里挖了個洞，在里面藏了一根胡蘿卜和一塊骨頭。

He wanted to see which animal would find them first.他想看看哪只動物先找到它們。

The rabbit was very cheerful and optimistic, and he threw himself into looking for the carrot, digging here and there, totally convinced that he would find it. 快樂且樂觀的兔子，他全身心地尋找胡蘿卜，到處挖掘，完全相信他會找到的。

But the dog was pessimistic, and after sniffing around for a bit, he lay down on the ground and began to complain how difficult it was to find one bone in such a big field.但是狗很悲觀，他嗅了一會兒之后，便躺在地上，開始抱怨在這么大的田野里找到一根骨頭是多么困難。

The rabbit dug for hours, and with every new hole the dog complained even more about how difficult this was, even for the rabbit. 兔子挖了好幾個小時，隨著不斷挖出的洞，狗愈發(fā)的抱怨這是多么困難，甚至抱怨起了兔子。

The rabbit, on the other hand, thought that each hole dug was one hole less that needed digging.而兔子認為挖出一個洞，那么需要挖的洞就少一個。

When there was no place in the whole field left to dig, the rabbit dug a tunnel to right under where the dog had been lying all that time. 當整個田野沒有地方可挖時，兔子挖了一條隧道，一直到狗躺著的地方。

There he found the carrot and the bone.在那里他找到了胡蘿卜和骨頭。

And this is how it was that the dog lost due to his pessimism. 由于悲觀情緒，狗就這樣輸了這場比賽。

Because, thanks to his great instinct, he had already found the right place at the very beginning!一開始由于本能他找到了正確的地點，但是沒找到骨頭，只是不斷抱怨。
