Answer:
1. People tend to amassl possessions, sometime being aware of doing so. Indeed they can have a delightful surprise when they find something useful, which they did not know they owned. Those who never have to change house become indiscriminate collectors of what can only be described as clutter. They leave unwanted objects in drawers, cupboards and attics for years, in the belief that they may one day need just those very things. As they grow old, people also accumulate belongings for two other reasons, lack of physical and mental energy, both of which are essential in turning out and throwing away and sentiment. Things owned for a long time are full of associations with the past, perhaps with the relatives who are dead, and so they gradually acquira a value beyond their true worth.
2. Something is collected deliberately in the home in an attempt to avoid waste. Among these, I would list string and brown paper, kept by thrifty people when a parcel has been opened, to save buying these two requisites. Collecting small items can easily become a mania. I know someone who always cuts out from newspapers sketches of model clothes that she would like to buy, if she had the money. As she is not rich, the chances that she will ever be able to afford such purchases are remote. But she is never sufficiently strong minded to be able to stop the practice. This is a 'harmless habit', but it litters up her desk to an extent that every time she opens it, loose bits of paper fall out in every direction.
3. Collecting as a serious hobby is quite different and has many advantages. It provides relaxation for leisure hours , as just looking at one's treasures is always a joy. One does not have to go out for amusement, since collection is housed at home. Whatever it consists of stamps, records, first edition of books, China glass, antique furniture, pictures,model cars, stuffed birds, toy animals, there is always something to do in connection with it, from finding the right place for the latest edition to verify facts in reference books. This hobby educated one not only in the chosen subject, but also in general matters which have some bearing on it.
Hope it helps you
