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