Honestly, there isn’t a specific side hustle that is best. Depends on your skills and abilities and you as an individual. At your age if you’re unsure, just experiment. Throw yourself into things and see what your good at… content creation, selling and buying goods, personal branding, editing video, digital marketing, AI content, Amazon FBA, e-commerce, the list goes on. Right now, you have the most valuable asset… “time”. So experiment and learn. Hopefully through that process something will trigger your interest.
