One afternoon, many years ago, I went to pick up my mother from work. I got there a little early so I   21  the car by the roadside and waited for her.
As I looked   22  the car window, there was a small park where I saw a little boy, around two years old,   23  freely on the grass as his mother watched from a short   24 . The boy had a big smile on his face   25  he had just been set free from some sort of   26 . The boy would then fall to the grass,   27 , and without hesitation or without looking back at his mother, run as fast as he could again, still with a   28  on his face.   
Kids, when they fall down, don't view their falling down as failure, but   29 , they treat it as a learning experience. They try and try again until they   30 . While I was touched by the boy's persistence, I was   31  touched by the manner in which he ran. With each attempt, he looked so   32  and so natural — no signs of fear, nervousness, or of being discouraged. His only   33  was to run freely and to do it as effectively as he could. He was just being a   34  — just being himself—being completely in the moment. He was not looking for   35  or was not worrying about whether   36  was watching. He didn't seem to be bothered by the fact that maybe someone would see him   37  and that it would be   38  if he did fall. No, all that   39  to him was to accomplish the task, to feel the experience of running fully and freely. I learned a lot from that   40  and experience, and have successfully brought that lesson with me in my many pursuits（追求) in life.
