20、There are many things we need to know but we do not learn at school．For example, if we want to use our money wisely（明智的）, we need to shop carefully．We need to know how to compare the prices of things in different shops．We need to be able to compare the quality of different brands（品牌）． We need to know how to make a choice（选择）when we shop．

Knowing how to make such choices is a “life skill”, and we need these skills if we want to live useful and happy lives．

Some of these choices are small．For example, will I take an apple for lunch or a pear? Will I go to school by bus or on foot? Will I wear the red T-shirt or the blue one to the movies? Other choices are more important．For example, will I eat healthy food for lunch or will I eat junk food because it is tastier? Will I work hard in all my classes or will I only work hard in the classes I enjoy? We make choices like this every day．

We have to realize that the choices we make can influence the rest of our lives．Just as importantly, our choices can also influence other people．The next time you decide to waste time in class, play a joke on someone or talk loudly at the movies, think about this: Who else does your choice influence?
