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(摘錄) 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 (饒舌音樂) 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 (投籃) 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(承認) when you don’t know something, and to learn something new.
And even when you’re struggling, even when you’re discouraged (泄氣), 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.

A habit is any action that we have performed so often that it becomes something that we do almost without thinking. Some of them are thought to be bad habits. People spend countless hours and dollars each year trying to get rid of these bad habits but often fail. Why? Change is hard work and there is no shortcut to achieve it. However, there is still some advice for you to follow.
First, look at why you do it. In other words, what’s the result of doing this thing? If your bad habit is shouting at people when you are unhappy or under pressure, what do you get from it? It may make you feel a little better for the moment. Or maybe you have a bad habit of leaving your homework undone. The result could be that you get more time to spend on the Internet!
Next, take a look on the other hand. What are you losing because of your habit? Shouting at other people is a bad habit because it makes people around you feel bad and unhappy. Leaving your homework undone is a bad habit because you may be punished by your teacher. Having more Internet time means that you are losing the chance to learn the things that you need to learn. When you think that way, you’ll find that it’s not wise to keep your bad habit! Now it is time to make a decision. What will you choose? I’m sure you will choose to do what you think is more important.
