If you are like millions of people around the world, the New Year brings with it new goals. But you get busy. Yet, your goal remains important. 1.
♦ Identify specific goals.
As you identify your goals, be specific. If a goal is too general, it may be hard to pursue, let alone achieve it. 2. That's a fine idea. Yet psychologists might say as a goal, it is too general. To make the goal more specific, you could sign up for a regular exercise class.

So, identify them, write them down and set for yourself time limits.

All over the world, and for many different reasons, there are millions of people who rarely or never eat meat. These people are called vegetarians. To people who eat meat, being a vegetarian may seem like a very strange thing, diets for several different reasons.
First, vegetarians have an enormous health advantage. One of the major health problems in modern societies is not too much protein but too much fat, especially in the form of animal fats. Medical evidence suggests that animal fats, including butter, contribute to the development of cholesterol in the human body. High amount of cholesterol seem to be part of the cause of heart disease. Most vegetarians have low level of cholesterol. High amounts of animal fats also seem to lead to certain kinds of cancer, and vegetarians are typically less vulnerable to these cancers than people who eat a lot of meat. Overall, studies comparing the health of vegetarians and meat-eaters show that the meat-eaters are twice as likely to die of heart disease as vegetarians are.
Better health is one reason that people choose to become vegetarians. Another reason is religion. Some religions forbid the eating of meat. The largest of these is the Hindu religion, which has about 600 million believers in the world. Although not all Hindus are vegetarian, many are, and there are many believers of other religions such Buddhism and even some Christian religions that also do not eat meat.
Many vegetarians do not eat meat simply because they do not like the taste of it. They have no religious or philosophical reasons; they just do not like meat. Another important reason that vegetarians give for not eating meat is the health advantages that were given above. Lastly, there are many people who do not eat meat because they just do not like the idea of killing animals for food. They believe that life, all life, is valuable , and that we do not have to destroy life to feed ourselves when there are other good sources of food.

Soccer is played by millions of people all over the world, but there have only been few players who were truly great. How did these players get that way—was it through training and practice, or are great players “born, not made”? First, these players came from places that have had famous stars in the past—players that a young boy can look up to and try to imitate. In the history of soccer, only six countries have ever won the World Cup—three from South America and three from western Europe. There has never been a great national team—or a really great player—from North America or from Asia. Second, these players have all had years of practice in the game. Alfredo Di Stefano was the son of a soccer player, as was Pele. Most players begin playing the game at the age of three or four.
Finally, many great players come from the same kind of neighborhood—a poor, crowded area where a boy’s dream is not to be a doctor, lawyer, or businessman, but to become a rich, famous athlete or entertainer. For example, Liverpool, which produced the Beetles, had one of the best English soccer teams in recent years. Pele practiced in street with a “ball” made of rags. And George Best learned the tricks that made him famous by bouncing the ball off a wall in the slums of Belfast.
All great players have a lot in common, but that doesn’t explain why they are great. Hundreds of boys played in those Brazilian streets, but only one became Pele. The greatest players are born with some unique that sets them apart from all the others.
