There was once a rich man who loved his little boy very much． He wanted to try his best to please him． So， he gave him a horse to ride， beautiful rooms to live in， pictures， books， toys and everything that money could buy． But for all days， the little boy was still unhappy． He wore a frown（皱眉） wherever he went， he always wished for something he did not have． The man didn't know how to make his son happy．

One day， a magician came to the man and said to him， "I can make your son happy and turn his frowns into smiles， but you must pay me a great price for telling him the secret．"

"All right．" said the man， "No matter what you ask for， I'll give you．" The magician took the boy into a secret room． He wrote something on a piece of paper， and then gave it to the boy． There on the paper came the words， "Do one kind thing for someone every day．" The boy followed the advice and became one of the happiest boys．

Only those who stop thinking about their own happiness can be truly happy．
