In my opinion hobbies are a very important part of our lives. These let us to relax from everyday's stress and are a way to keep us healthy.
If you don't have a hobby, you should starrt looking for one, so you can have an activity whoch you are likely to do in your spare time. If you already have an activity to do, but you don't really like it, you should look for one in which you can have pleasure with.
Like girls can lear baking, and boys can learn mechanic.
And if you can't decide or don't know what hobby to have, you can try different kinds of activities and then do which you like the most. There are a large variety of activities for different types of persons, such as painting and drawing for people who like art, volleyball or basketball for people who like playing with balls, or snowboard that is for poeple who like extreme sports and snow.
You can also motivate children to have a hobby showing them some of the hobbies you practice.
