天下只有两种人。比如一串葡萄到手，一种人挑最好的先吃，另一种人把最好的留到最后吃。照例第一种人应该乐观，因为他每吃一颗都是吃剩的葡萄里最好的；第二种人应该悲观，因为他每吃一颗都是吃剩的葡萄里最坏的。不过事实却适得其反，缘故是第二种人还有希望，第一种人只有回忆。 

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.
