Advice on freelance work

Hello, I am a young adult that is trying to save for college to ease my parents financial burden, yet my parents do not want me to work and instead focus in school. I still want to be able to help a bit. Any advice or ideas on how I can get some sort of income?
I have been selling stuff on websites like vinted but I’m looking for something a bit more steady. I have also started to learn a bit about the stock market.

I have a few skills like video editing, writing, speaking English and Portuguese. I am can also sing, act and dance but idk what can come from it besides the obvious.

Any ideas or advice? Thank you!
