Doing a hobby involves engaging in an activity that one enjoys during their free time. Hobbies can include a wide range of interests, such as painting, gardening, or playing a musical instrument. They provide a way to relax, express creativity, and develop new skills outside of work or daily responsibilities. Participating in a hobby can also foster social connections. Many people join clubs or groups related to their interests, such as book clubs or sports teams. This not only enhances the enjoyment of the hobby but also allows individuals to meet others with similar passions, creating a sense of community.
