/lit/ - Literature

I'm not particularly bright and I didn't get good grades in English, I'm a poor 24 year old NEET that's never had a job, I have a psycho mother, and divorced parents with a fairly shit upbringing, now live on my own
whenever I feel depressed and ask myself what the fuck I'm doing I feel like writing might be the answer; something about realistic, punchy dialogue lights a spark in me, as does good storytelling
I've barely even read any books, I'm more into films but getting a film made isn't exactly easy or cheap. I watched A Ballad of Buster Scruggs recently and it has these little book shots (pic related), and the writing is what inspired me to give it a shot once
so what are my chances of actually being able to write something worth a damn? is it just a matter of reading lots of books and learning how to write, with lots of practice?
I'm not that big on books (yet) but the writing in the pic is impressive to me, whether or not it is to you I'm not sure but if I could reach that level, I'd be pleased

TL;DR: how do I learn to write well?
