I gave you one example.. I got myself into programming when i was 14.. didn't even had a computer to start with hehehe other story. But is my go to if I need money.. i code stuff ^^
If you are more into art and creating pictures... totally not my field.. Patreon you can create art and get sponsored by your fans. Sorry to say it.. OnlyFans is also a form of income you can do from anywhere (and no, doesn't has to be porn oriented to make a killing). If you have a passion and can turn it into income, you have a rather good chance to succeed compared to stuff you hate to do. Isn't easy.. but.. the internet is most likely your best chance to create a income you can maintain world wide. Twitch game streamer, Youtuber, sculptor, product tester, traveler... become creative. I do Shibari beside and have a few female friends acting as my models. They do their own thing. ^^ Females have a few more options.. and again.. doesn't need to be pornographic at all.
You know best what you like to do and are good at.. see if you can turn that into a service on the internet. The start is always the hard part... and might need a few tries till you hit the bullseye. But if you don't try.. you will never hit the bullseye anyhow. Trying is part and if things don't pan out as planned, learn why, then it wasn't a failure in the first place, and try again. Making a mistake is only bad if you do not learn from it.. and learning is a good thing.. so don't let mistakes take you down, just learn from them.
If you want to learn coding, start with the simple Basic. Once you understand how the code flows, you can take on more complex languages.. again slowly.. if you try Assembler after Basic.. you will shoot yourself hehehe You will find similarities in all coding languages out there.. like with all, getting into a new topic is the hard part. Bite through it and is becomes easier with each program you write.. and the code gets also more and more complex.
