Avoid Busywork
Writing a novel (or, sometimes, even a short story) often requires a lot of work that isn’t writing. This could be research, or world-building no one will ever see, or getting your workspace set up in a way that’s conducive to your style. It might mean taking some time off and renting a yurt or something so you can dedicate yourself to the work. Or it might mean reading a ton of books in the same genre or category so you can get a feel for what’s current, what’s common, and what’s overdone.
All of that sort of work is sometimes necessary, but it can also become Busywork, and thus a way to feel like you’re accomplishing something without actually writing anything.
Writing Feng Shui
There’s an old cliché of someone procrastinating by obsessing over their workspace. They’ll get started on this novel as soon as they get the desk set up exactly the way they want, or as soon as they have perfect quiet, or as soon as they figure out the perfect word processing software that is ideal for their work style. They spend weeks ordering gadgets and arranging the furniture in their home office but never actually write anything.
That’s an obvious delaying tactic, but there are other ways of putting off the inevitable moment when you have to type CHAPTER ONE and begin the process of turning your ideas into a coherent narrative. This can come in the form of endless research, one source of info always leading to another, ad infinitum forever and ever world without end. Or it could mean working on minute details of your world-building backstory. Maybe you spend six months creating a language for your tribe of half-elk, half-men. Or maybe you spend a year sketching the coat of arms for every prominent family in your fictional city.
This stuff is fun, and it might serve a very good purpose for your creative process. But it can—not necessarily will, but can—also become a way of feeling like you’re doing good writing without actually, you know, writing anything.
Finding that balance can be challenging, but a good rule of thumb is simple: Did you actually write anything today? Then you’re not writing, no matter how much work you put into everything else.
One note: Drinking is never busywork and is always necessary to the creative process. And I will fight anyone who says otherwise <tears off shirt, screams>.
