天下隻有兩種人。比如一串葡萄到手，一種人挑最好的先吃，另一種人把最好的留到最後吃。照例第一種人應該樂觀，因為他每吃一顆都是吃剩的葡萄裏最好的；第二種人應該悲觀，因為他每吃一顆都是吃剩的葡萄裏最壞的。不過事實卻適得其反，緣故是第二種人還有希望，第一種人隻有回憶。
Only two kinds of people are living in the world. With a bunch of grapes, one kind of persons picks the best ones to eat first, and the other kind leaves the best to eat last. Accordingly, the former would be optimistic, because they ate the best grape every time; the later would be pessimistic, because each time they ate the worst. But the contrary is true: the second kind of people have hopes to go on along, while the first only have memories to recall.
