A group of boys stood around a tree. "What a tall tree!" they said to each other. "It would be exciting to climb to the top!"
The group of boys then decided to play a game to see who could climb to the top of the tree first. Their mothers were sitting not far away, looking on at their children as they played.
One of the climbers was an 8-year-old boy named David. He was the shortest child in the group. Nobody thought he would win.
Then the game started. All of the boys tried their best to climb as high as they could. Although the other boys climbed faster than David in the beginning, he reached the top of the tree fastest in the end.
His mother was proud (自豪的). She asked him. "David, how did you reach the top of the tree so quickly?"
"It was easy," David said. "The other children kept looking down as they climbed. When they knew how high they were, they were afraid of falling down. I, however, looked only up. When I saw how close I was, I kept going higher and higher until I reached the top."
It is true in life that if we just keep going forward without looking back, we are more likely to reach our goals (目标).
