Nowadays a lot of people have a certain interest in life - a hobby. We choose hobbies according to our characters and tastes.
I agree with the idea that you can be in harmony with yourself only if you have a hobby. Firstly, when we have a hobbies, our lives become more interesting and exciting. Secondly, our hobbies help us to choose our future professions because we learn a lot of new things. Thirdly, when we have hobbies, we are in high spirits and feel self-satisfied.
