It goes without saying that every person needs entertainment and enjoyment, free time and rest after hard work or sudy. All our activities can be divided into physical, intellectual and mental activities. Scientists prove that we can benefit from combining activities of different kinds as much as from having a rest. I study hard at school to achieve high results and get knowledge. I think that would have been impossible without activities I do in my free time. If you ask me how I usually spend my leisure time, I can say that I listen to music, spend time with my friends, cook or read books. Modern music is one of the things that makes me forget about everything. I like to listen to new records, tapes or compact disks of my favorite bands and to sing to myself when nobody hears me. Among my friends there are some who are also interested in music. Cooking is also one of my hobbies/ As for me, it is very interesting to create something very tasteful and looking attractive with irresistible flavour for the whole family. This hobby will be very helpful when becoming an adult and it may even be your second proffesion. One can't imagine modern life without books. I am not an exception. Reading is one of my favorite past times. Books help me to go away from life problems, to get into another world. Books pass over to us the knowledge and experience of previous generations, broaden our scope of vision. Regular reading enriches your knowledge about the world and helps to form your personality. The book is a faithful and undemanding friend of yours.
