Once there was a piano player in a bar(酒吧). People came just to hear him play. But one night, a lady asked him to sing a song.

"I don’t sing," said the man.

But the lady told the waiter, "I’m tired of listening to the piano. I want the player to sing!

The waiter shouted across the room, "Hey, friend! If you want to get paid, sing a song!’

So he did. He had never sung in public before. Now he was singing for the very first time! Nobody had ever heard the song Mona Lisa sung so beautifully!

He had talent(天赋) he was sitting on! He may have lived the rest of his life as a no-name piano player in a no-name bar. But once he found, by accident, that he could sing well, he went on working hard and became one of the best-known singers in the US. His name was Nat King Cole.

You, too, have skills and abilities. You may not feel that your talent is great, but it may be better than you think. With hard work, most skills can be improved. Besides, you may have no success at all if you just sit on your talent.
