Do the same, but with half a chapter and every day.
I mean the average writer without a physical disability should be able to compose about 600 words an hour on the very low end.
If you did that for 8 hours a day 5 days a week you'd have 2 rough draft novels a month.
My process usually goes like this
Inspiration from something leads to a concept or idea forming in my head.
I write the first chapter and in that chapter I try to justify, flesh out, and humanize my concept or idea. This chapter is typically an introduction or a short intro that the reader can use to set expectations for the rest of the book.
I write the next 3 chapters. If I can't get past these 3 chapters, chances are my concept is too weak, I don't like my characters, or my inspiration has faded too quickly to go on.
If I can get to about chapter 4 or 5, by then I've probably written enough to analyze my own story and construct more of the stories skeleton. I can start to really plot out and plan events for later chapters, and even dig into characters.
Basically
1.Think of Idea
2.Write opening set up.
3 Test idea for a few chapters.
And sure there are more complicated things I do between those steps, but in essence, that's what I do. Some people might think it's odd not to plan everything out from the start, but I feel like if I did that I'd never stop planning. I'd get stuck in planning. And if I allow myself to play and see where things go for a few chapters at the beginning, it can actually lead to more interesting concepts than what I might have planned for before I was in the midst of creating. Still, I know it's not for everyone.
I’ve written both prose and comics, and my overall method is to vomit up everything in various outlines and rough drafts, get feedback, rewrite with that feedback, keep writing, scrap the story, start from the ground up and rinse and repeat…. Sounds chaotic and time consuming (it is) but, I got one of my most complete and cohesive stories from this method. I think the key is finding the right person to edit your work. Someone who is a better writer and who will give you honest, constructive feedback.
1. I start by stretching in the morning.
2. I take a hearty breakfast.
3. BLOOD SACRIFICES FOR THE NARRATIVE ELDER GODS.
Well, no. Not precisely.
Now seriously.
I guess I'm a bit like you in that I don't have everything planned out from the start, but instead of starting with the first few chapters, I start with random 'important/climactic' scenes 
This might feel weird for someone without a plan, writing scenes without knowing when they take place in the story, but it works for me 
If I try to work from the beginning without a plan, I get stuck because I don't know where I'm going (even if I do still like my concept/characters) XD
I love to hand write on my iPad using GoodNotes. I can be anywhere and jot down ideas and do a rough draft. I use the ocr in GoodNotes to turn my printing to text. I copy the text and post in msword. All this on my iPad and saved in Dropbox.
Then I format and correct the words that weren’t converted right. Then I run it through Grammarly and then have it edited by my wife. Then make last minute changes and save to post.
I usually have a list of ideas for chapters that I use as a basic outline
So, I put my fingers on my keyboard, and words come out. Sometimes those words are even in English!
Taking tongue out of cheek for a moment, if I had to describe the quirks of my process, they would be:
Outlining. Pretty much every longer work I've ever created started with an outline, and the stories and characters come to life at this stage. If you read Re:Apotheosis, the process Kaguyama describes in chapter 3 is basically what I do. There's a bit of a nudge here and there, but otherwise my process of telling a story doesn't feel quite so much as making something up as discovering it.
I use WordPerfect, and I always compose double-spaced in Courier 12 point font. I'm old enough that I've been using WordPerfect since there was an actual competition for the office space between WordPerfect and Word, so to a degree it's a legacy application. That said, it does something no other word processor I've used does, outside of Notepad - using it feels like using a typewriter (so, to start a chapter, I hit the keys to centre the line, type the title, hit return, and the cursor is back on the left and I can just start typing). It's great - all I have to concentrate on is the words, and nothing else. As for the font thing, I can't really explain it. If I try composing in any other font, like Times New Roman or single spaced, it screws me up.
I very often will write the prologue and/or first chapter, and then the epilogue, and then I'll go back and write the other chapters in order. Not sure why I do it - it's like my brain needs an end point to work towards.
And here's Re:Apotheosis - if you read it, please do comment! There are a lot of twists and turns coming, and I'd kind of love to see how people are reacting and what they think will happen (and it will be interesting to see if they get it right...).
My cursive just looks like loops and squiggles. I can make out words in yours LOL but it is a mess LOL
The simplest way to explain my writing process would be something like this:
I create a detailed story in my mind: as if I'd be watching a movie or TV series from MC's perspective.
Then I do my best to write down what "I saw", with some changes or additions here and there.
My gay romance, slice-of-life story is an example, if somebody is willing to give it try:
Do you ever find you have stories in your head that never seem to work when you try to put them to paper?
I have 3 short stories cycling through my head at the moment but I'm not sure they will work right if I try to put them in words (plus I have 2 other projects I am currently writing)
Does squealing at cute parts crying when somethiing important happens in the book and its sad, or sobbing into my own pillow when I am emotionally durressed at my own deadlines, I created for myself count? No...
Okay.
I mainly write on my phone, but that’s only due to how my current PC is old and starting to show that age with slowing down and stuff. I am able to write with my phone, but I would probably be to do more with a PC or laptop, but they cost money.
I started out with fanfictions and do still write them every so often to help with my writing and with my creativity or with just some fun writing activity to do. I don’t write chapter-based fanfics that much anymore and mostly oneshots as anything can happen in them and they can be episodic in nature and considering I want to focus on my own stories they are easier to do as well.
I listen to music to help me draw my characters or picture scenes that I want to happen in the future of my stories though they’re mostly just ideas. I write notes down a lot as well, so I don’t lose track of any ideas. I have a lot of ideas, so it took me a while to focus on just one, but some of my other ideas have some of my favourite character designs or personality-wise characters that I’ve created that I can’t wait to get to writing it, but I like to focus on one thing or else I’ll be overwhelmed.
Here’s my novel if anyone wants to check it out. Don’t feel like you have to. It’s a supernatural/mystery with elements of crime in it.
