First the bad news: following the Novel Writing Process is only one of the tasks you must complete to write a novel.
In all, there are three of them:
The first of these is doing the actual planning and writing and revising of your novel, and the way you accomplish that is by following the step-by-step Novel Writing Process.
The second task is to learn your craft, or the "rules" of how to create characters, how to plot a novel, and so forth - and that is why the steps are backed up by in-depth sections explaining all these rules.
Finally, you need to read novels, particularly recently published novels from your chosen category of fiction. This will help you to learn both the art and the craft of how to write a novel.
If it feels like I have just tripled your workload, don't look at it that way.
The good news, you see, is that these three tasks - working on your own novel, learning the theory of novel writing as you go, and reading what other writers have done - feed off each other, creating a virtuous circle of improvement.
In other words, the best way to tackle the three separate jobs is in unison...
Learning the theory of how to write novels can be heavy-going all by itself, but practising the things you learn in your own planning and writing and revising, and seeing how other writers do it through reading, will bring the novel writing rules to life.
