　　　 In the United States, 30 percent of the adult population has a “weight problem.” To many people, the cause is clear: We eat too much. But scientific evidence (证明) does little to support this ides. Going back to the America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.

　　　 Several modern studies, moreover(此外), have shown that fatter people don’t eat more on average than thinner people. In fact, some investigations(调查), such as a 1960 study of 3,545 London office workers, report that, on balance, fat people eat less than slimmer(苗条) people.

　　　 Studies show that slim people are more active than fat people. A study by a research group at Stanford University School of Medicine found the following interesting facts.

　　　 The more the men run, the greater loss of body fat.

　　　 The more they run, the greater their increase in food intake(吸收).

　　　 Thus those who run the most eat the most, yet lose greatest amount of body fat. k+s-5#u

　　　 When people become good at doing the things they like they find themselves.

　　　 Many young people are good at doing things they do not like, many other young people would like to do something at which they are not good. Also, many do not think they are good at anything, and do not know what they would like to do. None of them are happy.

　　　 It is impossible to decide whether one likes something until one has tried it. Trying something new is important.

　　　 Give each idea a fair chance. If you have decided to try out something new and also decided how long you will stick to(坚持) it, then you can make a fair decision.

　　　 The best thing to judge is not the final goal, but the work it takes you to reach that goal. Almost everybody would like to be highly skilled in something, but becoming highly skilled at anything call for(要求) a great deal of time and effort.

　　　 Finding oneself means not only discovering what one is good at and what one likes; it also means discovering what one is not good at and does not like.

　　　 So trying some thing and failing can have its good side. It tells you that you are not fit for that particular area(特别领域) and should not use it as your goal.

　　　 Habits, whether good or bad, are gradually formed(逐渐形成). When a person does a certain thing, he is impelled(迫使) by some unseen force to do the same thing repeatedly, thus a habit is formed. Once a habit is formed, it is difficult, and sometimes impossible to get rid of(消除). It is therefore very important that we should pay great attention to the formation of habits. Children form bad habits, some of which remain as long as they live, and sometimes they become ruined by their bad habits.

　　　 There are other habits which, when formed in early life, are of great help. Many successful men say that much of their success has something to do with certain early habits, such as early rising(早起), honesty and thoroughness(彻底). k+s-5#u　

　　　 Among the habits which children should not form are laziness, lying, stealing and so on. These are all easily-formed habits. Unfortunately older persons often form habits which ought to have been avoided.

　　　 We should keep away from all these bad habits, and try to form such habits as will prove to be good for ourselves and others.
