This is not a complete list of what you can do in your free time. To make the process of choosing a hobby easier, you should pay your attention to a few key points. First - do not engage in a hobby through force or against your will.
Think about what you particularly like to do. Maybe you like cooking and can invent new recipes. Start learning cuisines, sign up for cooking classes and add original recipes in the cookbook.
Remember the circles and sections that you visited as a child. It is possible that you had some particular interest, for example singing, but you failed to develop it probably because of shortage of time. Try to continue training after enrolling yourself in an art studio for adults or work under the guidance of a vocal coach.
See what your friends are addicted to and try to do something with your favourite company. For example, travel to interesting historical festivals in the community. Even if the interests of friends do not coincide with yours, you will be able to significantly expand the list of possible hobbies.
Find interesting courses or workshops after signing up for a trial lesson. Some centres offer special training courses in which you can explore the different crafts and techniques. For example, after visiting a few classes, you will learn the basics of scrap-booking, decoupage, painting, acrylic or glass-case.
If you are not good in creating something with your own hands and you do not even see a special talent in you, think about collecting items for example records of your favourite artist, stamps or coins. This can be a very exciting experience. You can collect vintage clothing and perfume bottles, limited cosmetic products and labels, old postcards and modern paintings.
