I know that feeling. When I was young, my family lived overseas. I lived in Indonesia for a few years. And my mother, she didn't have the money to send me where all the American kids went to school, but she thought it was important for me to keep up with an American education. So she decided to teach me extra lessons herself, Monday through Friday. But because she had to go to work, the only time she could do it was at 4:30 in the morning.

　　Now, as you might imagine, I wasn't too happy about getting up that early. And a lot of times, I'd fall asleep right there at the kitchen table. But whenever I'd complain, my mother would just give me one of those looks and she'd say, "This is no picnic for me either, buster." (Laughter.)

　　So I know that some of you are still adjusting to being back at school. But I'm here today because I have something important to discuss with you. I'm here because I want to talk with you about your education and what's expected of all of you in this new school year.

　　Now, I've given a lot of speeches about education. And I've talked about responsibility a lot.

　　I've talked about teachers' responsibility for inspiring students and pushing you to learn.

　　I've talked about your parents' responsibility for making sure you stay on track, and you get your homework done, and don't spend every waking hour in front of the TV or with the Xbox.

　　I've talked a lot about your government's responsibility for setting high standards, and supporting teachers and principals, and turning around schools that aren't working, where students aren't getting the opportunities that they deserve.

　　But at the end of the day, we can have the most dedicated teachers, the most supportive parents, the best schools in the world -- and none of it will make a difference, none of it will matter unless all of you fulfill your responsibilities, unless you show up to those schools, unless you pay attention to those teachers, unless you listen to your parents and grandparents and other adults and put in the hard work it takes to succeed. That's what I want to focus on today: the responsibility each of you has for your education.

　　I want to start with the responsibility you have to yourself. Every single one of you has something that you're good at. Every single one of you has something to offer. And you have a responsibility to yourself to discover what that is. That's the opportunity an education can provide.

　　Maybe you could be a great writer -- maybe even good enough to write a book or articles in a newspaper -- but you might not know it until you write that English paper -- that English class paper that's assigned to you. Maybe you could be an innovator or an inventor -- maybe even good enough to come up with the next iPhone or the new medicine or vaccine -- but you might not know it until you do your project for your science class. Maybe you could be a mayor or a senator or a Supreme Court justice -- but you might not know that until you join student government or the debate team.

　　And no matter what you want to do with your life, I guarantee that you'll need an education to do it. You want to be a doctor, or a teacher, or a police officer? You want to be a nurse or an architect, a lawyer or a member of our military? You're going to need a good education for every single one of those careers. You cannot drop out of school and just drop into a good job. You've got to train for it and work for it and learn for it.

　　And this isn't just important for your own life and your own future. What you make of your education will decide nothing less than the future of this country. The future of America depends on you. What you're learning in school today will determine whether we as a nation can meet our greatest challenges in the future.

　　You'll need the knowledge and problem-solving skills you learn in science and math to cure diseases like cancer and AIDS, and to develop new energy technologies and protect our environment. You'll need the insights and critical-thinking skills you gain in history and social studies to fight poverty and homelessness, crime and discrimination, and make our nation more fair and more free. You'll need the creativity and ingenuity you develop in all your classes to build new companies that will create new jobs and boost our economy.

　　We need every single one of you to develop your talents and your skills and your intellect so you can help us old folks solve our most difficult problems. If you don't do that -- if you quit on school -- you're not just quitting on yourself, you're quitting on your country.

　　Now, I know it's not always easy to do well in school. I know a lot of you have challenges in your lives right now that can make it hard to focus on your schoolwork.

　　I get it. I know what it's like. My father left my family when I was two years old, and I was raised by a single mom who had to work and who struggled at times to pay the bills and wasn't always able to give us the things that other kids had. There were times when I missed having a father in my life. There were times when I was lonely and I felt like I didn't fit in.

　　So I wasn't always as focused as I should have been on school, and I did some things I'm not proud of, and I got in more trouble than I should have. And my life could have easily taken a turn for the worse.

　　But I was -- I was lucky. I got a lot of second chances, and I had the opportunity to go to college and law school and follow my dreams. My wife, our First Lady Michelle Obama, she has a similar story. Neither of her parents had gone to college, and they didn't have a lot of money. But they worked hard, and she worked hard, so that she could go to the best schools in this country.

　　Some of you might not have those advantages. Maybe you don't have adults in your life who give you the support that you need. Maybe someone in your family has lost their job and there's not enough money to go around. Maybe you live in a neighborhood where you don't feel safe, or have friends who are pressuring you to do things you know aren't right.

　　But at the end of the day, the circumstances of your life -- what you look like, where you come from, how much money you have, what you've got going on at home -- none of that is an excuse for neglecting your homework or having a bad attitude in school. That's no excuse for talking back to your teacher, or cutting class, or dropping out of school. There is no excuse for not trying.

　　Where you are right now doesn't have to determine where you'll end up. No one's written your destiny for you, because here in America, you write your own destiny. You make your own future.

　　That's what young people like you are doing every day, all across America.

　　Young people like Jazmin Perez, from Roma, Texas. Jazmin didn't speak English when she first started school. Neither of her parents had gone to college. But she worked hard, earned good grades, and got a scholarship to Brown University -- is now in graduate school, studying public health, on her way to becoming Dr. Jazmin Perez.

　　I'm thinking about Andoni Schultz, from Los Altos, California, who's fought brain cancer since he was three. He's had to endure all sorts of treatments and surgeries, one of which affected his memory, so it took him much longer -- hundreds of extra hours -- to do his schoolwork. But he never fell behind. He's headed to college this fall.

　　And then there's Shantell Steve, from my hometown of Chicago, Illinois. Even when bouncing from foster home to foster home in the toughest neighborhoods in the city, she managed to get a job at a local health care center, start a program to keep young people out of gangs, and she's on track to graduate high school with honors and go on to college. And Jazmin, Andoni, and Shantell aren't any different from any of you. They face challenges in their lives just like you do. In some cases they've got it a lot worse off than many of you. But they refused to give up. They chose to take responsibility for their lives, for their education, and set goals for themselves. And I expect all of you to do the same.

　　That's why today I'm calling on each of you to set your own goals for your education -- and do everything you can to meet them. Your goal can be something as simple as doing all your homework, paying attention in class, or spending some time each day reading a book. Maybe you'll decide to get involved in an extracurricular activity, or volunteer in your community. Maybe you'll decide to stand up for kids who are being teased or bullied because of who they are or how they look, because you believe, like I do, that all young people deserve a safe environment to study and learn. Maybe you'll decide to take better care of yourself so you can be more ready to learn. And along those lines, by the way, I hope all of you are washing your hands a lot, and that you stay home from school when you don't feel well, so we can keep people from getting the flu this fall and winter.

　　But whatever you resolve to do, I want you to commit to it. I want you to really work at it. I know that sometimes you get that sense from TV that you can be rich and successful without any hard work -- that your ticket to success is through rapping or basketball or being a reality TV star. Chances are you're not going to be any of those things.

　　The truth is, being successful is hard. You won't love every subject that you study. You won't click with every teacher that you have. Not every homework assignment will seem completely relevant to your life right at this minute. And you won't necessarily succeed at everything the first time you try.

　　That's okay. Some of the most successful people in the world are the ones who've had the most failures. J.K. Rowling's -- who wrote Harry Potter -- her first Harry Potter book was rejected 12 times before it was finally published. Michael Jordan was cut from his high school basketball team. He lost hundreds of games and missed thousands of shots during his career. But he once said, "I have failed over and over and over again in my life. And that's why I succeed."

　　These people succeeded because they understood that you can't let your failures define you -- you have to let your failures teach you. You have to let them show you what to do differently the next time. So if you get into trouble, that doesn't mean you're a troublemaker, it means you need to try harder to act right. If you get a bad grade, that doesn't mean you're stupid, it just means you need to spend more time studying.

　　No one's born being good at all things. You become good at things through hard work. You're not a varsity athlete the first time you play a new sport. You don't hit every note the first time you sing a song. You've got to practice. The same principle applies to your schoolwork. You might have to do a math problem a few times before you get it right. You might have to read something a few times before you understand it. You definitely have to do a few drafts of a paper before it's good enough to hand in.

　　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 because it shows you have the courage to admit when you don't know something, and that then allows you to learn something new. So find an adult that you trust -- a parent, a grandparent or teacher, a coach or a counselor -- and ask them to help you stay on track to meet your goals.

　　And even when you're struggling, even when you're discouraged, 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.

　　The story of America isn't about people who quit when things got tough. It's about people who kept going, who tried harder, who loved their country too much to do anything less than their best.

　　It's the story of students who sat where you sit 250 years ago, and went on to wage a revolution and they founded this nation. Young people. Students who sat where you sit 75 years ago who overcame a Depression and won a world war; who fought for civil rights and put a man on the moon. Students who sat where you sit 20 years ago who founded Google and Twitter and Facebook and changed the way we communicate with each other.

　　So today, I want to ask all of you, what's your contribution going to be? What problems are you going to solve? What discoveries will you make? What will a President who comes here in 20 or 50 or 100 years say about what all of you did for this country?

　　Now, your families, your teachers, and I are doing everything we can to make sure you have the education you need to answer these questions. I'm working hard to fix up your classrooms and get you the books and the equipment and the computers you need to learn. But you've got to do your part, too. So I expect all of you to get serious this year. I expect you to put your best effort into everything you do. I expect great things from each of you. So don't let us down. Don't let your family down or your country down. Most of all, don't let yourself down. Make us all proud.

　　Thank you very much, everybody. God bless you. God bless America. Thank you.

　　奧巴馬人物評價：

　　正面評價

　　挪威諾貝爾委員會將2009年諾貝爾和平獎授予奧巴馬，

　　以表彰他在促進國際外交和各國人民合作所作出的非凡努力。

　　對于奧巴馬獲諾貝爾和平獎，多數(shù)觀點持肯定態(tài)度，認為他作為世界上最強大軍事力量的領導者以及他所倡導的無核化理念，是全球和平的希望，還指出他是唯一一位向穆斯林國家表示友善的美國總統(tǒng)。[13]

　　負面評價

　　2013年11月18日-20日，CNN和全球市場調查機構ORC聯(lián)合對全美843個成年人進行了電話抽樣調查。結果顯示，只有40%的人認為貝拉克·侯賽因·奧巴馬能有效管理聯(lián)邦政府，該數(shù)字比2013年6月的調查下降了12個百分點。53%的人認為奧巴馬不誠實、不值得信賴，這是CNN民調中首次發(fā)現(xiàn)超半數(shù)美國人持有這樣的看法。此外，56%的受訪者說，奧巴馬不是自己崇拜的人。

　　美國《紳士季刊》總共列出了25位最無影響力名人，奧巴馬位列第17位，因為他“什么也沒做”。[44]

　　《紐約郵報》調侃稱，奧巴馬是“陷入僵局的總司令”。[44]

　　俄羅斯《今日報》稱，奧巴馬以“失敗的政治家”和“無法堅持自己立場”而入選。專家們認為，奧巴馬承諾的太多，講得很華麗，實際上卻什么也沒有做。因為不成功的醫(yī)保改革、移民政策及不善于維護自己在國際政治中的地位，尤其是在處理敘利亞問題時的失誤，使得奧巴馬的執(zhí)政路變得相對坎坷。[27]

　　美國前總統(tǒng)克林頓則稱奧巴馬是美國歷史上最糟糕的總統(tǒng)。

　　《時代》：民調顯示奧巴馬成戰(zhàn)后最差總統(tǒng)。[45]

　　美國昆尼皮亞克大學民調研究所2日發(fā)布一項民調結果，貝拉克·奧巴馬以33%的得票率被評為第二次世界大戰(zhàn)以來美國“最糟糕的總統(tǒng)”[46] 。

　　2014年8月28日，奧巴馬在新聞發(fā)布會上談及俄烏以及打擊“伊拉克和沙姆伊斯蘭國”(ISIS)等問題。輿論不僅對他的觀點有所不滿，甚至認為他的西裝十分滑稽。人們的注意力都集中在總統(tǒng)的淺黃色西裝上(如圖)，而不是他對烏克蘭和敘利亞問題的看法。美國媒體甚至調侃稱，稱其穿傻帽西裝。[47]

　　美國反戰(zhàn)組織“粉色代碼”(CODEPINK)和“立即行動起來結束戰(zhàn)爭和種族主義聯(lián)盟”(ANSWER Coalition)2014年9月25日在白宮門口舉行游行示威，抗議總統(tǒng)奧巴馬對敘利亞和伊拉克發(fā)動空襲行動，批評美國中東政策是“伊斯蘭國”發(fā)展壯大的原因之一，也是問題所在。
