TEN-YEAR-OLD Barack Obama was one of the only three black students at his school in Hawaii, US.
He felt very different from most other students. White girls wanted to touch his hair. A white boy asked
him whether his father ate people.

star at Harvard. Later, he became only the third black senator (参议员) in US history. During his race to the

than a white America or a black America.

(判断) by the color of his skin (皮肤), but by the content of his character," wrote ABC news.

What’s your idea about success? Some people say that beginners have all the luck, while others believe that success 1 only with practice. In fact, I feel both of these statements (陈述) are not true all the time. Each is true in some ways 2 not in others. For example, I went to a drawing competition many years ago and 3 surprisingly. As a prize, I got a film ticket to see “Titanic”. I was really 4 because it was the first time I had taken part in any competition. Thinking that I might be lucky again, I 5 joining in other art competitions. But the result was that I 6 won again. I accepted the fact that the other people had a 7 artistic ability than I did. Art was not something I was especially interested in and I had never practiced the different art skills. So, the 8 I produced were not of a very high standard. These experiences taught me a lot. Though I might have been lucky 9 , I also need to put in hard work. As we know, 10 makes perfect. So I believe success builds on less luck and chance.
