      Many people have discovered that hobbies can be profitable as well as fun. Some people have such fine

collections of bottles, flags, buttons or shells that others are willing to pay to see them or they offer to buy

their collections for large sums of money.

      Some of the best collections are owned by people who started their hobbies as young boys or girls. Some

of the things that American children like to collect are stamps and dolls. Older people also save stamps, but

they collect coins and things made of glass more often than dolls.

      Painting, writing and taking photographs are the best examples of hobbies that may become occupations.

Every writer, artist and photographer probably started as a hobbyist before becoming a professional. Other

hobbies that could be profitable include cooking, sewing and making things out of wood.

      Many doctors believe that hobbies help to make our lives more enjoyable. They believe that people who

raise fish or collect recorders are too busy to spend their time worrying. Doctors also think that an active

person, such as a baseball player, should have a restful hobby such as reading, while a person who sits at a

desk all day should have lively hobbies such as tennis, golf or swimming. Most people in the United States

agree with the doctor. It is difficult to find an American who does not have a favorite hobby.
