In March 2008, I told my friends: I was going to shut down my law practice and travel around the world in a year. What's more, I'd do it without taking any flights or making a single advance (预先的) reservation. Some friends offered support and encouragement, while others were doubtful. Once I'd said the words, there was no turning back. It took months to shut down my law practice and get things in order.

    There really wasn't any great reason why I wanted to circle the world. I simply wanted to do something fun and different. When I had this plan, I didn't plan for it to lead to a life on the road forever. I was planning to come back, open a new law practice and write a hugely successful book about my travels. Before I left, I started a travel blog, which served as a way to take notes for the book.

    Once I set off on my trip in December 2008, I found that travelling without using planes was not easy. It took seven days and nights on trains to get from Moscow to Beijing. Sometimes, I wouldn't see a village or a human being for 10 hours. I had a whole cabin to myself from the second day of that journey.

    It turned out that travelling with no reservations was far less difficult than I had imagined. Pulling into a city on a bus with a bag, looking in a guidebook for a few suggestions of accommodations (住宿), and then finding an empty room was never a problem.

    Soon after I started this adventure, I realised that my return to the US would be temporary (暂时的). About three months into my journey, I realised that I didn't want to go back to my old life. The world is so wonderful and I wanted to see as much of it as I could.

    Finding motivation (动机), especially study motivation, is not always easy. Here are some ways of doing it.

    Offer yourself encouragement.

    Yes, you should give yourself a prize or some kind of reward when you've done a task. Remember, you have to know the exact conditions that you need to meet in order to receive the wonderful cake.

    You need to feel confident about your studies. I am sure all of us have succeeded on several occasions. Remember these past successes and you will feel more motivated to continue!

    Write down your goals.

    Don't just think about them, don't just say them, write them down! And that's why you find salesmen always want you to write something down before you actually buy something. By writing your name down, you are in a sense giving your support for their cause. If then you are asked to buy what they are selling, you are more likely to do that than if you hadn't signed the paper!

    See your goals.

    Put them up on the wall and paste (粘贴) small post-it notes all over the place. You have to keep on reminding yourself of the purpose behind your studies and what type of results you're expecting to achieve.

    Michael is American high school student. Like many schoolmates, Michael used (eat) breakfast while it was still dark. But that changed when his high school followed a new time schedule two years ago.

    The problem of school start time has become one of the most important issues are discussed in public. A growing number of sleep-related studies have pointed to high school students' need more sleep. More than half of the (child) between ages 15 and 17, as is shown by researches, sleep for 7 or (few) hours per night.

    Children like to stay up at night, usually going to bed late and waking up late in the morning. These habits may (cause) by the biology (生理), according to researchers. They think changing the sleep schedule of children (be) unable to work, "Only going to bed earlier will not (certain) make someone less tired in the early morning hours, "said a researcher. He also added, "Kids' lack (缺乏) of enough sleep is a growing public health problem in our nation. We need to work out ways to deal with . Putting off school start time may be helpful."

    Last month, my classmate, John, caught bad cold. The news which he was running a high fever and ordinary medicine hadn't worked on him immediate reached everybody in our class. Some recorded the English lessons for him so that he could keep up on his studies. Our English teacher calls on him at weekends. Thanks to everybody's kind help, he failed to falling behind in his studies and finally came back to the class. With love, no illness or difficulty are terrible. Love and help are two-way streets. Our classmates were offered John help partly because he had always been a warm-heart boy. So I realise that when we help others, we are helping us.

    A smile will tell people around you that you are a kind and friendly person. However, many people don't smile because they think they have ugly teeth. For example, one of my classmates, Mike, doesn't have very nice teeth, so that is why he seldom opens his mouth. He even says that he has lost confidence because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit tooth problems from their parents, while others' teeth are damaged because of bad habits, like heavy smoking, eating too much sugar or not brushing teeth often. If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of them.

    Smiling can help you feel more confident and make people think of you as a more friendly person. If you want to keep healthy, you should not only smile but also laugh. An Indian doctor called Kataria said that young children should laugh about 30 times a day, while adults should laugh between 7 and 15 times a day. So please take this chance to smile and laugh now.
