A Hobby Makes Your Life Much More Interesting
Our life would be hard without rest and recreation. People have quite different ideas of how to spend their free time. For some of them the only way to relax is watching TV or drinking beer. But other people use their spare time getting maximum benefit from it. If you enjoy doing some activity in your free time, thеn you have a hobby. A person's hobbies are not connected with his profession, but they are practiced for fun and enjoyment. A hobby gives one the opportunity of acquiring substantial skill, knowledge and experience. A hobby is a kind of self-expression and the way to understand other people and the whole world. A person's hobbies depend on his age, intelligence level, character and personal interests. What is interesting to one person can be trivial or boring to another. That's why some people prefer reading, cooking, knitting, collecting, playing a musical instrument, painting, photography, fishkeeping or playing computer games while others prefer dancing, travelling, camping or sports.
Collecting things is a very popular hobby and it may deal with almost any subject. Some people collect stamps, coins, badges, books, clocks or toys. Other people collect beer cans, key rings, stones, matchboxes, thimbles and all sorts of things. Once you've got a small collection you keep adding to it. Some people don't even remember how their collection started but now their house is crammed full of different knick-knacks which they can't use but keep for the sake of having them. But some people collect valuable and rare things as they consider it to be a good investment of their money.
If you are active and tired of town life, if you long for changes and want to get away from civilization, then camping is for you. It is a cheap way to rest, to improve your health, to train yourself physically and to enjoy nature. Some people prefer more extreme camping when they have to survive out-of-doors, orient themselves, obtain food from the wild, build shelters and adapt themselves to extremely cold weather. They learn to overcome any obstacles and become strong and self-reliant.
Ecotourism is becoming popular and fashionable all over the world, especially with people who try to damage the environment as little as possible. Tourists visit places of natural beauty and they usually travel on foot, by bicycle or boat so that there is no pollution. They stay in local houses or hotels and eat local food. Their aim is to enjoy nature, to experience the local culture and to get unforgettable impressions without polluting and wasting or destroying natural resources. They must keep places that they visit clean and safe. The principles of eco-tourism are 'Leave nothing behind you except footprints and take nothing away except photographs' and 'Take as much care of the places that you visit as you take of your own home'. If people remember these simple rules, we will be able to save our planet and to conserve the wildlife.
A hobby plays a very important educational, simulational and psychological role, makes you stronger physically and mentally, helps you escape from reality, improve your knowledge, broaden your mind, develop your skills and gain a better understanding of how the world works.
