There are many hobbies that can be cultivated in leisure time, such as reading, flowers, photography, singing...but the feelings that can be cultivated in leisure time must be accumulated and slowed down by understanding and interest. Develop slowly. For example: you can learn calligraphy to calm your heart and develop a calm and introverted mood; for example, you can do charity activities and become a bright person who can see the good and evil in the world.
