　　Some people would argue that life experience is important for being a motivational speaker, but an 11-year-old kid from Pakistan is proving that all you really need is an inspirational speech and confidence.

　　At just 11 years of age, Hammad Safi has accomplished what most of us won't be able to do in a lifetime. He is the youngest motivational speaker in Pakistan, and probably the world, a free writer, TV anchor and a lecturer at a University , where he teaches students twice his age. He has been referred to as a "super kid", a "child extraordinaire", "motivational guru" and even "the little genius of Pakistan".

　　"He is not an ordinary child. I have seen abilities in him. That's why I have appointed special teachers for him," Safi's father, Abdul Rehman Khan, said, "I want him to become a special leader. I'm very proud... For his abilities, for his intelligence.

　　 Abdul's description may seem exaggerated (夸张的）- he is Hammad's father after all - but the boy is indeed capable beyond his years. How many 11-year-olds do you know that can command the attention of thousands of adults while speaking on serious topics like success, life challenges or responsibility? Hammad can, and he does it with ease, relying on his great charm, practiced hand gestures and a confidence that attracts his audiences greatly.

　　"A few months ago I was really disappointed with life... I was thinking about suicide, because there are no jobs and no success in life," a student said, "Then I saw a movie of Hammad Safi. I thought if an 11-year-old child can do anything, why can't I?"

　　That is what makes Safi so special, his power to get his message across and inspire people much older than him.

　　Many in Pakistan are astonished by Hammad's self-confidence and his ability to lecture on important subjects, but there are also those who believe that this role is depriving the boy of his childhood.

　　29. Which statement about Hammad Safi is not correct?

A. His audience is much older than he is.
