juggling a side hustle/side bis as a teen

I just came from indian flex subreddit and also have been thinking from quite sometime to have a side hustle and earn small income at the beginning.. but just start actually earning something on my own.. something online and which takes only 1-2 hrs of my day.. I have no knowledge regarding finance or any skill.. I still gotta develop it all but I know I want to.. so just wanna ask if anyone is genuinely making some money out of a part time online job or anything pls guide me as well🙏

I am currently living with my parents preparing for an exam.. but me earning in this field would take almost 8-9 yrs😭 so I also wanna grow outside of that..

also does linkedin help in anyway?
