I remember there was a little story let me ponder for long: five fingers to fight because they are the length of missing, one has to compete against, so they thought of a way, that is, brought a small ball, who should pick up the ball Who is the winner, when the brothers worked hard, want to first pick up the ball, but the days of the later, no one can pick up the ball, the brothers who are very dull of mind, the weakness of their own , complaining, criticism, feel that they are no use, nothing to do anything, the brothers who no sleep a night and, after the anti then, the next morning, the sun out of the ground plane of that moment, brothers say in unison:"We test with the next bar."

记得曾经有一个小故事让我深思良久：五只手指头打架，因为它们长短不齐，却要一争高下，于是它们想到了一个办法，就是拿来一个小球，谁先拿起小球谁就是赢家，那时几个兄弟奋力拼搏，都想先拿起小球，可是日子一天天的过去了，谁也没能拿起小球，兄弟们的心情都十分沉闷，对自己的软弱无能，抱怨，批评，觉得自己很没有用，做什么都一事无成，兄弟们一晚都没睡好，辗转反则，第二天清晨，在太阳跳出地平面的那一瞬，兄弟们异口同声的说：&我们一起试下吧&。
