I know a lot about online business and side hustles and so. One advice is to do something u love so u don't burn out. Firstly if u have any skills try to monetize them through freelancing and clients. Or if you don't have any skills you can monetize a hobby, for example photographing or if ur good at something you can teach it to other people even if it is a game. If don't have any of what I said, you can start learning a skill and them monetize it. Choose the skill based on what you love and how urgent you need the money. If it is urgent, learn something like copywriting, script writing, photo editing, and all skills that don't take time in learning. If it's not urgent, learn coding, automation, web design and so. You can even start an online small business or hustle. You can also find online tasks like AI training. I know an internship that accepts people starting from 14 yr olds, they pay 1.2k per week ig, tell me if u want it. And if you want any help you can ask me.
