Do you want to be successful in everything you do? If so, then how? Here is an example.
There was a farmer who   36  corn（玉米）all his life. Each year he took his corn to the market. Then each time his corn was chosen as the   37  and won the first prize.
One year a newspaper reporter interviewed him and learned something surprising about how he grew it. The farmer   38  his seed（做种子的) corn to his neighbors.
"How can you share your best seed corn with your neighbors?" the reporter asked. "You know they are taking part in the   39  with you each year."
"Why, sir," said the farmer, "didn't you know? The   40  picks up pollen (花粉) from the corn and moves it quickly from field to field. If my neighbors grow   41  corn, cross-pollination (异花传粉) will affect the quality of my corn. So if I want to grow good corn, I must help my neighbors to grow good corn. "
The farmer knows much about the connection of life. His corn cannot improve unless his neighbor's corn improves.
As a great man says, "We make a living by what we grow; we make a life by what we give." We can't   42  without food, clothes, and many other things. However, a meaningful life is not decided by how much we can get,   43  by how much we can give others. Giving, instead of taking, makes us    44   from other animals.
So those who choose to live well must help others to live well and those who choose to be happy must help others to find   45  in their life.
