I grew up in a small town. I was only ten years old when my dad gave me the responsibility of feeding the chickens and cleaning up the stable (马厩). He believed it was important for me to have those jobs to learn responsibility. Then, when I was 22, I found a job in Natchbill at a country music club called the Natchbill Palace. I washed dishes and cooked from 4:00 pm to 9:00 pm and then went on stage and sang until 2:00 in the morning. It wasn’t long before I became known as a singing cook. I had been rejected so many times by record companies that it was hard not to be discouraged.

One night, a woman executive (董事) from a company named Warner Brothers Records came to hear me sing. When the show was over, we sat down and talked and after she left, I said to myself it was one more rejection. A few weeks later, my manager received a phone call — Warner Brothers wanted to sign me to a record deal. Soon after, I had my first record in June 1986. It sold over 2 million copies. My best efforts had gone into every job I’ve ever held. It was the sense of responsibility that made me feel like a man.
