Which is good earning skills for us?

Hi guys I'm searching new money making skill. Which will totally abstain from my addiction. Something like difficult or good reward for brain like gaming. I read here some people have YouTube channel but don't know how YouTube work or how they make videos also i want to hide my identity so i feel insecure. I read about coding but again don't know what is coding and how it work.
If you give some advice its very thankful
