生命的高度
一位科学家做过这样一个实验：把许多跳蚤放到一个广口瓶里，瓶口用透明玻璃盖住。刚开始时，跳蚤们拼命地往外跳，但都被玻璃碰了下来。一段时间以后，即使把玻璃取下来那些跳蚤也只能跳瓶子那么高。昔日的跳高冠军，被封闭在了自己界定的高度上。
也许你会嘲笑跳蚤的愚蠢。但认真想一想，我们有没有像跳蚤一样呢？当在某一高度上失败碰壁的次数太多了，就对自己能不能超越这个高度产生怀疑，就认定自己不可能再有新的突破了。就像跳蚤一样，我们缺乏的并不是跳出瓶子的能力，而是跳出瓶子的信心和勇气。
生命所能达到的高度，往往就是我们心理上为自己界定的高度。
The Height We Can Reach in Our Life
□□A scientist once performed an experiment as follows: after having put a large number of fleas into a jar, he covered it with a piece of transparent glass. In the beginning, the fleas tried to jump out of that jar, so they jumped as high as they could. But they were always hit back by the glass cover despite of their persistent efforts, After a period of time, even when the glass cover was removed, the fleas could jump no higher than the bottle. Unfortunately, the former champions of high jump were limited/confined to a height fixated by themselves in the end.
□□You may laugh at the fleas for their foolishness. But let’s take a second consideration, “Did we once behave as the fleas”? When we have failed to do something or have got a bump on the nose many times at a certain height, we tend to doubt our own abilities to get over the height and decide that we can make no more breakthroughs. Just like the fleas, what we lack is not the ability to jump out of the bottle but the confidence and courage to do so.
□□The height we can reach in our life is usually what we set for ourselves in our minds.
