Hobbies are very important to a person. Without having any hobby, life won't be as colorful as it should be. I have a variety of hobbies, such as collecting stamps, playing musical instruments, reading, and doing sport activities. When I am free, I will spend time on my hobbies. When I am in a blue mood, I will also do my hobbies to cheer myself up. Hobbies can help us improve our moods.
