Article: A young man approached the foreman of a logging crew and asked for a job. "That depends," replied the foreman. "Let's see you fell this tree." The young man stepped forward and skillfully felled a great tree. Impressed, the foreman said, "You can start Monday." Monday, Tuesday, Wednesday, Thursday went by -- and on Thursday afternoon the foreman approached the young man and said, "You can pick up your wages on the way out today." Shocked, the young man replied, "I thought you would pay me on Friday." "Normally we do," said the foreman. "But we're letting you go today because you've fallen behind. Our daily felling charts show that you've dropped from first place on Monday to the last place today." "But I'm quite hardworking," the young man disagreed. "I am the first to arrive and the last to leave and even have worked through my coffee breaks!" The foreman thought for a minute and then asked "Have you sharpened your axe?" The young man replied, "No, sir. I've been working too hard to take time for that!" Our lives are like that. We sometimes get so busy that we don't take time to "sharpen" the axe. In today's world it seems that everyone is busier than ever, but less happy than ever. Why is that? Could it be that we have forgotten how to stay sharp? There's nothing wrong with hard work. But we shouldn't get so busy that we ignore the truly important things in life. We all need time to relax, to think, to learn and to grow. If we don't take time to sharpen the axe, we will become dull and lose our effectiveness.

Article: Studying abroad will shape you in various ways. You will learn things you never would have if you had stayed home. When you are young and unattached, you should travel. Besides, you just might save a large sum of money. College is expensive in the United States. It's cheap or free in other countries even for foreigners, so why not get out of here and come back smarter? More and more American students are currently studying at German colleges. That number has increased 20% over the last three years. Living costs are about $7,000 a year, which is even lower than in other European countries. Germany encourages international students. They create a multicultural landscape that benefits German students as well. According to a new report, Germany is home to six of the world's 100 best universities. These schools offer around 900 degrees completely in English and many German students speak the language. You could be part of Finland's excellent education system. The Finns charge no tuition and offer a number of courses purely in English. They would be happy for you to add flavor to their school scene. Cost of living there is high. Be prepared for frosty winters that far north, but you will get that sweet midnight sun in the summer. Many other European nations offer cheap or free college for foreign students, but if South America is more your thing, try Brazil. Most of the education will take place in Portuguese, so if that is in your plan you can study near beautiful beaches and jungles. The University of Sao Paulo and State University of Campinas are both highly ranked internationally. Your money will go a long way there, too. Many of the lessons you will learn will be outside the classroom. Living on the economy in a foreign country will keep you on your toes. You will learn new customs, how to bargain, stay safe, budget and become more flexible with people. There is no better way to learn a language than by immersing yourself in it. At first, it will be the toughest thing you have ever done. Eventually, it will become second nature.
