How do I become a Web3 developer and more dumb question from a newbie

Hey! So I know absolutely nothing about development. I know nothing about code at all, I'm a marketer.

I'm 23 years old and lately I've been fantasising with the idea of learning web3 development, mainly because I'm very deep into the NFT ecosystem (and also seeing how much these developers make is tempting, not gonna lie).

I've always been quite capable, not a genius or anything but I'm not dumb either, in case this is important (is it?).

So I guess you can imagine my questions... How do I start this journey? Would you recommend it or maybe I should focus on web3 marketing? How hard is it? Can you do this without formal education? And how many years of learning would I need in order to get a job doing this?

I'd love your comments and advice in general. I've a feeling that this post is extremely naive from me but I guess you need to start somewhere, right? Thanks for your help!
