What to study?

[Pruned6674]

Well, I'm living in an advanced country but expensive life, I'm quite minimalistic and don't need much. 19M right now working as a mix of Customer Service and Helpdesk nothing too professional but I don't hate it. Anyway, there are two things I like most in my life computers & money, I used to game a lot but damn I quit it all at once just by selling my pc gaming and now I'm using a second-hand laptop and browsing the internet. I like to make money online and nulled is adventurous but only side-job can't really make a stable lifestyle out of it. I wanted to learn economics since it sounds interesting but way too known in our country and low salaries then my second choice is computers which I really like too but programming is for smart people who like mathematics and physics; that's way above my level. And IT sounds good but that's such a huge thing and the salaries don't necessarily well and I'm not sure what I can study, doing computers stuff and making good money I think that's fine.
All my life I was sure I will be a millionaire or something because I was so obsessed and passionate about this, my goal wasn't necessarily to conquer the world just to simply retire very early (around 30s) and enjoy simple and minimalistic life. But that's when I was 16 and now it's been 3 years and nothing changed, I literally have zero formal skills and my confidence regarding this thing is quite lost so I gotta find something to guarantee myself a better future.
I'm shy but working on it, I'm lazy but always find the shorter and easier paths, I'm not smart just average and that's pretty much all.
I usually never do things like that but I guess you can see how desperate I am and btw sorry for bad English.
