Mr. Smith had a 8-year-old son named Tony, who enjoyed listening to music very much. So he bought a piano to Tony, hoping that he can become a famous pianist one day. The little boy put her heart into practicing the piano day after day and seemed enjoy every minute of it. However, half a year later, he told his father that he was tiring of practicing the piano. Heard this, Mr. Smith said, “Tony, it is one thing to be fond of listening to music, and it is another thing to perform skillful by yourself. You can never play the piano well even if you don’t practice more.”
