You don't have to find a part-time job yourself, you can also develop yourself. Isn't there an online shop in Waves now? You can purchase your own goods to open an online shop, or you can do physical business, such as printing business, but you need upfront funds. If you don't have money, you can go to a group that sells reference materials on the bulletin board, and you can find sales skills to make your pockets swell. As for being a tutor, many college students will consider it, so as your brother said upstairs, you can experience the feeling of being a teacher, apply what you have learned and let your students learn something. You can get a sense of accomplishment. Why not?
