How can I get started as a 15 year old with little money?

I'm looking to make a bit of money while I'm in school that won't require 24/7 attention. I don't currently have a job so the money I have is mainly from saving and some family work. I've tried to make money in the past om fiverr, I've tried shopify and creating custom websites for drop-servicing. On fiverr I made around $15 aud and that's all I've been able to make. Idk if this is the right place to ask but any help would be awesome.
