You should start your journey with a list of assets you have. And at the moment, that's probably just a bit of software knowledge. You are at the bottom of the barrel. Many people are ahead of you in the queue, so if you can professionalize your assets and software techniques, you can build tutorials, ebooks, and video series about them as you build up your assets.
You can't really just ask where to start, though. It's like you don't have any dreams or interests that have managed to lead you anywhere productive so far. (would you look yourself in the mirror and admit you have no imagination or dreams? lol) Everyone has their own interests; some people say this, and some people say that. Go where your heart and brain lead you. Its not hard, the internet is filled with poor solutions to problems that sell well.
Just do what you can where you are with what you have, and keep improving. Learning and earning.
