Mrs. Obama spoke to the graduates of Martin Luther King Jr. High School on Saturday in her only high school commencement(毕业典礼)speech this year. The ceremony took place in the gymnasium of Tennessee State University.

The first lady told the 170 graduates that she spent too much of her time in college focusing on academic achievements. While her success in college and law school led to a good job, she said, she ended up focusing on public service. “My message to you today is that don’t waste a minute living  someone else’s dream,” she said. “It takes a lot of real work to discover what brings you joy and you won’t find what you love simply by checking mailboxes or surfing the net.”

She said MLK reminded her of her own high school experience in Chicago. “My No.1 goal was to go to a high school that would push me and challenge me,” she said. “I wanted to go somewhere that would celebrate achievement. Unfortunately, schools like this don’t exist for every kid.” she said. “You are blessed.”

The first lady told graduates that failure may be a part of their college lives and careers, and that how they respond determines what they  will become. “That’s when you find out what you’re really made of in those hard times,” she said. “But you can only do that if you’re willing to put yourself in a position where you might fail.” Overcoming difficulties has been the mark of many great people, she said, “Oprah was demoted(降职)from her first job as a news reporter, and now she doesn’t even need a last name,” she said of media giant Oprah Winfrey “And then there’s this guy Barack Obama, I could take up a whole afternoon talking about his failures. He lost his first race for Congress”, the first lady joked, “and now he gets to call himself my husband.”

Going green seems to be fad (时尚)for a lot of people these days. Whether that is good or bad, we can’t really say, but for the two of us, going green is not a fad but a lifestyle.

On April 22, 2011, we decided to go green every single day for an entire year. This meant doing 365 different green things, and it also meant challenging ourselves to go green beyond easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task.

With the idea of going green every single day for a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps.

Over the course of Our Green Year, we completely changed our lifestyle. We now shop at organic(有机的)stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punish ed.

Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.
