I have read lots of How-to-Write-books. This is one of the important ones. Many books will tell you how to structure your scenes, how to write dialog etc, but very few tell you how the process of writing actually works. I know that everybody works differently, but I followed the technique in this book and it works amazingly well: (in short, you'll need to read to book to get the details) Frist, write the whole book from start to finish, without worrying about editing or inconsistencies ar actually anything. Then, write a 2000 word synopsis, until you are satisfied with the story. Then rewrite from start. The reason this works for me is that I have a tendency to wory too long over a certain scene or even a word. This technique allows me to just not care if the writing is lousy, just get on with the story. You'll have a novel written in about 3 months, BUT it's only the first draft and it's bound to be embarrasinly poor. But now you have the story, and you start again, and now when you now what you are doing you can agonize over the words and scenes until they work. If you do it the other way round, you spend a lot of time writing scenes that never make it to the final draft.
You'll need other books on writing, too, this is not the bible of writing, but certainly one of the best.
