There is a well-known story about a farmer1 found an eagle(鹰) egg. The story reminds us of the importance of developing our full potential(潜力).
One day, a hardworking 2 found an eagle's egg lying on the ground of his farm. He was in a hurry 3 he paid no attention to it and 4placed it together with all the chicken eggs. After several days, the egg hatched(孵化)and the little eagle 5 into the world.
The eagle thought he was 6 same as the other chickens, 7 the eagle pecked(啄食)and dug for worms. He ran about and sometimes jumped around, flying a few 8 in the air like the chickens. Over the years, the eagle grew old and tired. One day he saw a splendid bird 9 overhead, and asked, “ 10 is that?” “That's the king of the 11— the bald eagle,” replied a chicken. “The sky is her home. We're chickens -- our home is 12 the farm.”
And so the eagle lived and died 13 a chicken, for that's what he believed he was.
Are you an eagle tha 14 like a chicken? 15 , many people have great talents bu 16 bring them to use. Actually, we 17 make our talents take off by developing our character strengths. Suppose there was a young man who 18 in the world. He asked questions about his environment, explored new neighborhoods where he lived, and soon he mentally mapped out the city he lived in. He used his curiosity to make the 19 of his talents for spatial(空间的)intelligence.
When we use our character strengths, we will 20 that we are eagles.
