get in the real estate game work hard as fuck and move up, lock up a small niche community and you're skr8.
start as an appraiser and work your way up.
also run some small side hustles in the meantime, making clothes or buying and selling online, etc. you can make a little money at it and learn about owning/running your own shit, how to source shit and supply-chain management and finding drop-shippers and things like that. then find a profitable industry in which to use those skills/savings and cash in.
also you're young so always be thinking about the future. learning a lot about technology and coding and things like that will put you a step ahead down the road.
if you really wanna make money, you might as well go to college i think it would just make things easier, but if you don't want to you can still succeed, but for now you need to try to find a job at some small business where you can learn about how things work and then work your ass off, as in like 60 hours a week, and live frugally. show people you are serious about learning and working and they will respect you, teach you, and when opportunities arise you will be first on their list.
at least i think thats how it works/ thats what im planning after graduating art school haha im pretty much using art school to learn production and entrepreneurial skills at this point, planning on setting up my own shit eventually.
Sparknotes: college makes things easier(and is fun), you don't have to go if you really don't want to but you better know your shit and work hard as hell if you wanna make anything.
