As someone who wants to become self-published some day this is pretty cool.
Honestly, there's no better time to start than today. Writing is one of those things that the more you do it, the better you get at it. Don't listen to anyone that tells you that you need to plan what you are doing before you do it. Planning is the death of doing.
Just get started writing. Pound out 5,000 or 10,000 words and get the skeleton of your story written. Share it with people. Get feedback. Let them tear it apart. Then get back into the story. Tear it apart. Don't rewrite it. Just take something that was undeveloped and run with it. Add a chapter or two in between elements that could be better expanded, and keep doing that until you are at 20,000 words. Keep sharing the revisions with the people you trust and like. Then go back to revision. Keep adding more until you feel like it's solid.
At 5,000 to 10,000 words a day, you'll have a novel in two weeks.
You don't have to know where you are going. Just explore where the story takes you. There's an awful lot of shit just sitting in your head and waiting to get out. Don't look outward for inspiration, look inward. You know good stories. You know how to tell good stories. You just have to get people invested in the story you want to tell. The story you want to tell is worth hearing. It's worth reading, and it's worth buying. Just get it out of your head for others to read. All you have to do is get your reader invested. That's not hard.
As for grammar, spelling, etc. It doesn't really matter while you are writing. That's for the editing phase. A good story doesn't come from good grammar and spelling. It comes from trying to share an idea with someone else. That's all. You have ideas. You have a ton of them. All of them can be good if you explore them and work at them.
As someone who wants to become self-published some day this is pretty cool. I'd be willing to buy a copy of your book when it's finished.
