D Finding solutions 1 Read the article. Then check (/) the chapters that might be in Chelsea Thomson's book. 1 ]How to Use Less Energy 5 LHOW to Have More Garbage 2 ]How to Waste Time 6 ]How to Use Your Car Less Often 3 ]How to Recycle More 7UWhere to Buy Local Food 4 ]Buy More Than You Need 8 | Kinds of Food You Can Grow at Home Dear Readers, My new book, Going Completely Green, is finished! As the title says, I decided to go completely green for a month - no electricity, no running water, no car, no phone, no computer! I didn't even use anything with batteries. It was very difficult, and I decided to write a book about my experience. During the day, I wrote on paper with a pencil. When I wanted to sharpen my pencil, I remenmbered my pencil sharpener uses electricity. T had to sharpen it with a knife! At night, I used a candle for light. I washed all of my clothes by hand with water from the river behind my house, and then I put them on a clothesline to dry. I walked to a local farm to buy food. I ate mostly fruits and vegetables. I only ate meat about five times, and I cooked it over a fire in my yard. The hardest part was not talking to friends and family on the phone or emailing them. My best friend lives an hour away by car, so l didn't communicate with her at all. In my opinion, it is impossible to live completely green for a long time, but there are many things you can do. Now, I try to work with the lights off for most of the day. I'm driving my car again, but I try to walk or ride my bike when I only have to go a short distance.I buy more local food now, too. I have to use my computer for work, but I use it for fewer hours each day. l also turn it off when I'm not home. There are many things you can do to use less energy and water. This book will help you learn how to live a greener life. If you follow the steps in my book, you'Il really help the environment. Oh, and if you buy my book, you might want to read it by candlelight to save energy! Chelsea Thomson 2 Read the article again.

What moabos people Successน bte s Who do you think is the most successful? Who do you think is the least Successful? In order to answer these questions, we first need to define success. Everyone has a different definition. Many of us place great value on performance, on achievements, or on Others goals. SUCSS reaching various associate success with material goods, measuring it by how much one can acquire. Others measure success by how much they can contribute to the well-being of their families, or to the community and society in general There are many other definitions, but mostly success is associated with becoming rich, famous, and respected at work. Yet, it doesnt have to be that way. Being successful could mean simply being satisfied with oneself and one's career. For many people, a successful person is someone who feels that his or her work and life in general offer an exceptionally high degree of satisfactions. But how does one get from here to there? How does one reach this feeling of satisfaction with life and career? It seems that successful people consistently do two things: * They use their natural abilities in their work. * They set career and life goals. In other words, successfuนl people choose careers where they can use their natural abilities, or do what comes naturally to them. For example, successful teachers are people who instinctively know how to help people learn, and the best doctors are those who know how to listen to people. Successful people know where they are starting from, and what direction they want to give their lives and careers, even if it is something as simple and wonderful as raising a happy family. What are your natural abilities? What are your career and life goals? If you can answer these questions, you are on your way to having a Successful career and life.
