whats a good side hustle you can do online without having a big budget to start out

Im 15 still in school and want to make some money

I tried dropshipping it went very well i made 3k sales in the first month (€400 profit) but then my business got shut down since i was selling reps.

I was thinking dropshipping but is there anything else i can do from home that i dont need much money to start out (willing to spend money when i get some profit coming in)
