     Have successful people ever felt sad? Do they have any "secrets" to success? The answers to

these questions can be found in US president Barack Obama's "back to school" speech. Here is

an excerpt (摘录) from his speech.

     I know that sometimes, you get the sense that you can be rich and successful without any hard work-

that your ticket to success is through rapping (饶舌音乐) or basketball or being a TV star, when chances

are, you're not going to be any of those things.

     But the truth is, being successful is hard. You won't love every subject you study. Not all the homework

will seem completely important to your life right this minute. And you may not succeed at everything the first

time you try.

     That's OK. Some of the most successful people in the world are the ones who've had the most failures.

JK Rowling's first Harry Potter book was turned down 12 times before it finally came out. Michael Jordan

was cut from his high school basketball team, and he lost hundreds of games and missed thousands of shots

(投篮) during his career. But he once said, "I have failed over and over and over again in my life. And that is

why I succeed."

     These people succeeded because they understand that you can't let your failures beat you-you have to let

them teach you. You have to let them show you what to do differently next time.

     No one's born being good at things. You become good at things through hard work.

     Don't be afraid to ask questions. Don't be afraid to ask for help when you need it. I do that every day.

Asking for help isn't a sign of weakness; it's a sign of strength. It shows you have the courage to admit (承

认) when you don't know something, and to learn something new.

     And even when you're struggling, even when you're discouraged (泄气), and you feel like other people

have given up on you-don't ever give up on yourself. Because when you give up on yourself, you give up on

your country.
