I want to get into literature, but dont know where to being from

i do not know if this is the right place to ask this question, but here we go

I'm 17M who never read a book in his entire life
I recently started feeling like improving my English, reading actual books and maybe even writing poetry
its too much probably but I wanna do everything slowly anyways
how do I actually being with all this, do I watch youtube or do I just go with the flow, read whatever I find and maybe soon I'll realize what I actually want to do
but the 2nd approach seems not soo good to me
I wanna know all the basics there are, to actually get started
and did I mention my vocabulary ain't that great??
today it self I actually started writing new words, 1-3 every day, I'm planning that
anything u guys would suggest?? i appreciate every suggestion
