If you have chosen a hobby according to your character and taste you are lucky because your life becomes more interesting. Hobbies are divided into four large classes: doing things, making things, collecting things, and learning things. The most popular of all hobby groups is doing things. It includes a wide variety of activities. Playing different computer games are becoming more and more popular. Making things includes drawing, painting, making sculpture, designing costumes, handicrafts. 
Some hobbyists write music or play musical instruments. Almost everyone collects something at some period in his life: stamps, coins, matchboxes, books, records, postcards, toys, watches. Some collections have no real value. People with a good deal of money often collect paintings, rare books and other art objects. Often such private collections are given to museums, libraries and public galleries. No matter what kind of hobby a person has, he always has the opportunity of learning from it. By reading about the things he is interested in, he is adding to what he knows.
