One afternoon many years ago, I sat down on a chair in a park and watched a little boy, around 2 years old,      1.    (run) freely on the grass as his mother watched from a short distance．The boy would fall to the grass, get up, and without looking back at his mother, run as fast as he could as if nothing     2.   ( happen)．

When kids fall down, they don't think of the fall as      3.     failure. Instead, they consider      4.     as a learning experience．They try and try again     5.     they succeed．

I was also touched by the way he ran. With each attempt, he looked so      6.   (confidence) and natural．He only wanted to run freely and to do it as well as he could．He was just being a child--- being himself completely at the moment．He never gave up．Each time he fell, he     7.     got up again, as if he knew that falling down was     8.     (simple) a part of life．

He was not looking for others' smiles, or worrying    9.    whether someone was watching or not.    10.    he wanted was to run and to feel the experience of running fully and freely．I learned a lot from the experience.
