有人把一只跳蚤放在广口瓶中,用透明的盖子盖上。跳蚤在瓶子里不停的跳动,并撞到了盖子。经过数次撞盖子后,跳蚤不再跳到足以撞到盖子的高度了。拿掉盖子后,跳蚤虽然继续在跳,但不会跳出广口瓶以外。因为跳蚤已经调节了自己跳的高度,而且适应这种情况,不再改变。有什么样的目标,就有什么样的人生。尽管许多人都明白自己该做些什么,但是目标的局限性束缚了他们的才能。他们 Someone put a flea in a jar, covered with a transparent lid. The flea kept beating in the bottle and hit the lid. After several hits the flea stopped jumping enough to hit the height of the lid. After removing the lid, the flea continues to jump, but does not jump beyond the jar. Because fleas have adjusted their height of jumping, and adapt to this situation, no change.
