seeking for online sidehustle/job

Hi, I'm currently 19 years old and for some reason I'm so stupid I can't make money, my current skill is only digital illustration and I've never gotten any commission at all, in 2020 I uploaded gigs on fiver for 1 semester without any customers I failed, in 2023 I created a meme account for youtube shorts and also failed, is there any job that prioritizes problem solving that if studied only takes 2-3 years? thanks

What are the other subset of this skill
That you know are important to people

Take your skill (digital illustration) and then focus on specific needs people might have that AI may not be able to do for them.

Can you create digital illustrations for books/graphic novels? Can you create custom illustrations for local business websites? Can you create artwork for video games? Target customers/partners in specific areas/industries using the internet.
