Many people like collecting things. For some people, they don't throw away the unwanted things because they believe they may be useful one day. For others, especially old people, old things keep memories of the past and old friends. They carry a special meaning. Collecting things can easily become a hobby. When people really put heart into it, the hobby can do them much good.
Collecting makes people happy during their free time. Collectors do not have to go outside for fun. They keep collections at home: stamps, books, pictures, model cars, toy animals, etc. It is always enjoyable to look at the collections.
Collecting keeps people busy, too. When there is a new piece of collection, they need to find the right place for it. Sometimes this new piece pushes them to read. In this way, collectors learn new things from the hobby.
Collecting also gives people a reason to make new friends. Collectors may want to meet other collectors to show new findings, to share stories, and to get advice. So the hobby leads to travel. Collectors take trips to meet new friends. Their group of friends grows. After years of sharing, collectors may become closer friends.
