PROBLEM: Article: The students were not exactly overjoyed that Steve Jobs was going to be the speaker. Everyone wanted Bill Clinton. After all, his daughter Chelsea had gone to school at Stanford. So every year that Clinton was not named speaker was a disappointment no matter who it was. Graduation is not in order. It wasn't until we started walking into the stadium that I even realized that I'm actually graduating right now. Stanford has this tradition, the wacky walk, where everyone dresses up in different clothes or throws Frisbees or beach balls. I'm from the South so I had a seersucker suit shipped in from back home in Georgia. Some other guys dressed up as iPods. It was good fun. That was an interesting contrast to Job's speech. He started talking about being fired from Apple and then having cancer, how doctors told him he was going to die and how he was adopted as a baby into a family with parents who never went to college --- an unusual experience that played out over his life. His speech was very raw and very open. He told us that he gets up every morning and looks in the mirror and asks "If today were the last day of my life, would I want to do what I am about to do today?" "If the answer is not for too many days in a row", he said, "it's time to make a change. That has really driven a lot of my decisions since then. When I've reached certain points in my job where I'm not very excited to get to work early or stay late or work on something over the weekend or all night. When I lose that excitement then it's probably not the right thing for me anymore". He said, "Your time is limited, so don't waste it living someone else's life." Exactly. Death is a great motivator. You have to get out there and do something because some day you won't be there. Of all the advice I've received I rely on that the most.

PROBLEM: Article: Let's pretend we're sailing down the Rhine River on a pleasure boat. The Rhine is one of the main waterways of Germany, and the river traffic is heavy. It's interesting to watch the many boats going up and down the river. But the river traffic is not nearly so interesting as the beautiful scenery along the banks and hillsides. The boat is passing many old castles. We can see people working in the vineyards on the hillsides. There are vineyards as far as the eye can see. Wine from the Rhine Valley is famous all over the world. Suddenly our boat slows down and begins to turn a little. We are coming to a sharp bend in the river. On our right we can see a rocky cliff over 400 feet high. At first it looks quite ordinary, but there is nothing ordinary about it. There are many stories, poems, and songs about the cliff. We are looking at the Lorelei. Then someone on the boat begins to sing in German, the song of the Lorelei. It is a song about a beautiful siren who has lured many sailors to their deaths. The siren is supposed to sit on the rock combing her long golden hair and singing. The sailors who hear her forget to steer , and the current of river hurls their boats on the rocks and dashes them to pieces. Soon other people on the boat begin to sing. The beautiful song adds to special magic to the moment, and you begin to realize why so many people have made this trip down the Rhine to see the rock of the Lorelei.

PROBLEM: Article: Nowadays the U.S. students are sleepy in school because they spend too much time texting, playing video games, watching TV and using the media in other ways. "Heavy media use interferes with sleep by reducing sleep duration, making it harder to fall asleep, and lowering sleep quality," Meilan Zhang, an assistant professor at the University of Texas at El Paso, wrote in her research review in the journal, Sleep Medicine. But the relationship between youth's media use and sleep is not so simple, said Michael Gradisar, who authored both that review and the Sleep Medicine meta-analysis. "Technology use is the new evidence when we are trying to answer 'Why are school-age children sleeping less?'" said Mr. Gradisar, an associate professor of psychology at Flinders University in Adelaide, Australia. There may be safe limits to technology use, Mr. Gradisar stated. For instance, recent research results indicate that using a bright screen for an hour before bed or even playing violent video games for less than that will not necessarily interfere with teenagers' sleep, he wrote. But longer periods of usage can be harmful to sleep, Mr. Gradisar added. Rather than delaying school start times, he said, the first step should be educating parents about limiting the hours that their children are using technology before bed, and enforcing a consistent bedtime. Early school start times are also commonly blamed for students' sleepiness, especially for adolescents. Secondary schools around the nation and the world have been delaying start times, often with positive results. Mr. Minnich of the TIMSS and PIRLS International Study Center hesitated to put blame to any particular factor. But he did think that cost-saving measures to consolidate bus routes might help explain U.S. students' sleepiness. "For those children who board the bus first, they must get up earlier, may end up sleeping on the way to school, and may end up arriving at school sleepy." he said.
