Sarah J. Maas has sold tens of millions of copies, and everyone loves to reduce her productivity to a headline: insane word counts, 18-hour writing binges, a woman who apparently doesn’t sleep. That story is catchy, but it’s a decoy.

The more interesting story — the one buried in over a decade of interviews, essays, and Q&As — is about sequence. Maas has a repeatable way of moving a book from a vague feeling to a finished manuscript, and it has almost nothing to do with raw stamina. It’s about which parts of the job she lets be messy, which parts she keeps sacred, and when she switches between them. If you write fiction, that sequence is worth stealing regardless of your genre or your daily word count.

She starts with a feeling, not a premise

Maas doesn’t talk about her stories beginning as premises or high concepts. She talks about them arriving as images and music.

Throne of Glass reportedly began when she was listening to the score for Cinderella’s escape from the ball and thought the music felt too dark for a fairy tale — which led her to imagine an assassin fleeing after a failed attempt on a prince’s life. Crescent City started even further from a plot: while listening to music on a flight, she says she saw the climax of House of Earth and Blood play out in her head before she knew who the characters were or what world they lived in. She then worked backward to figure out who could end up in that scene.

Both are emotional images with no scaffolding yet — the plot, world, and characters get built afterward, in service of protecting that original feeling.

The takeaway for a working writer is that you don’t need a fully-formed premise to start developing a book. A strong enough image, mood, or musical association can function as your compass even before you know the plot. Maas has said she treats a book’s playlist as something close to an outline: not a list of events, but an emotional and tonal map she can return to when she loses the thread.

Her outlines are real, but they’re not the boss

Maas falls midway between a plotter and a pantser. She plans enough to know her destinations, and then drafts to discover the road between them.

Early in her career, she described her default approach as “pantsing” — holding the major plot points in her head and inventing the connective tissue as she wrote. Working with a publisher on the Throne of Glass series later required her to submit detailed outlines in advance, something she has said was useful but also occasionally frustrating. The frustration is explained by something she said a few years later: when she tried to force characters down a path the outline demanded, she ended up with material she had to cut and rewrite anyway, because it didn’t feel true to who those characters had become.

So her process runs on two layers at once. One layer is conscious architecture — the outline, the beats she’s contracted to hit, the shape a publisher expects. The other is a discovery layer, where character psychology gets veto power over the plan. When the two conflict, the outline loses.

This is a genuinely practical model for anyone who’s been told they have to pick a camp. You can hold a destination firmly — the ending, the big turn, the thematic point you’re building toward — while treating the specific route as provisional. The outline exists to keep you oriented, not to overrule what the story is telling you once you’re in it.

The first draft’s only job is to exist

When Maas describes drafting itself, she’s unambiguous about what matters and what doesn’t. In a 2010 essay, she put herself in the “frenzy” camp of writers: no fixed daily quotas during an active draft, long immersive stretches (i.e., 12,000-word days, 18-hour sessions), momentum treated as the priority over almost everything else. She’s said the first several chapters of a book often exist mainly to help her find its voice, pace, and world — meaning she goes in already expecting to throw them out or rewrite them later.

Note though, those insane stretches are anecdotes about peak intensity during a specific kind of sprint, not a documented daily norm. In her earlier interviews, from 2009 to 2012, she describes a much more modest and sustainable habit: at least 1,000 words on a normal writing day, with deliberate breaks built in to avoid burning out.

The 1,000-word floor is a maintenance practice — the thing that keeps a project alive on an ordinary week. The high-intensity sprint is what happens when a full draft needs to get out of her head before it dissolves.

For a writer trying to build a sustainable practice, the useful move is giving yourself explicit permission to draft badly. Maas prioritizes plot, character, and momentum in a first draft, and defers sentence-level quality, thematic polish, and even some fact-checking until later. The draft’s job is to produce a complete skeleton she can then operate on, ugly as it may be.

Research comes after the scene, not before it

One of the more counterintuitive pieces of her process is how she handles research. Maas has described deep research into history, combat, material culture, clothing, food, and daily life across her books. But she doesn’t do it up front. In a 2010 essay, she said she’ll frequently draft a scene first and go back afterward to verify or add a specific detail.

Research done in the middle of drafting is one of the easiest ways to kill momentum. Falling down a rabbit hole about medieval siege weaponry mid-scene can end a writing session that would otherwise have produced three more pages. By backfilling detail after the scene already exists, Maas protects the draft’s forward motion and still ends up with a well-textured, plausible world — she just builds the texture in a second pass rather than the first.

This is a genuinely transferable habit. If you find yourself constantly breaking flow to fact-check something small, try leaving a bracketed placeholder — [check X] — and moving on. You can verify it once the scene (or the whole draft) exists.

Caveat: If you’re someone who needs the atmospheric texture to move forward and feel like you’re in the story, then please do what helps you move your story forward. The objective is always use whatever strategy that keeps you moving forward.

Revision is where the real discipline lives

If drafting is where Maas gives herself permission to be loose, revision is where she becomes ruthless. The clearest evidence is the pre-publication history of what became Throne of Glass: by her own account, an early version of roughly 240,000 words lost about 100,000 words, then another 20,000, along with an entire plotline and characters she’d grown attached to. She’s described the manuscript going through approximately five major rewrites before it became the published book.

It’s a story about a fast, rough first draft followed by editorial pressure applied without much sentimentality. The willingness to cut a plotline you love, or a character you’ve spent months with, is arguably the actual engine of her output. Speed gives her a complete story to diagnose. The willingness to cut gives that story its final formidable shape.

Her revision process also has a specific, almost old-fashioned ritual attached to it. She’s said she drafts in Microsoft Word but prints out revision letters from editors, agents, or critique partners so she can read them on paper and handwrite her response plan. She’s described handwriting as something that helps her actually internalize both the criticism and her plan for addressing it, rather than skimming past it on a screen.

Early in her career, that feedback loop started even before agents and editors were involved — she posted serialized drafts on FictionPress and used reader reactions to figure out what was working. The specific platform is dated, but the underlying mechanism (get a draft in front of readers early, use their reactions as diagnostic data) still holds up.

A working routine, not a magical one

It’s worth saying plainly: Maas’s actual daily schedule is the least mystical part of any of this, and the interviews suggest it changed over time as her workload changed. Around 2015, and again in interviews describing her 2018 workload, she described a day that started with administrative work — email, social media, cover and interior review, logistics — with actual writing or editing beginning after lunch and running until dinner, extended later when deadlines demanded it. During heavy publishing periods, that extended across seven-day weeks.

The environment she’s described building around that routine is mostly about protecting immersion: a home office she can close herself into, music (often classical or film scores) as a consistent atmosphere, and in at least one interview, a fun personal quirk: a mirror behind her desk that she used to test facial expressions and body language for dialogue scenes.

Though there isn’t a permanent, universal Sarah J. Maas schedule, what’s stable across more than a decade of interviews is the sequence: a spark, then some loose planning, then fast drafting, backfilling research and finally ending in a crescendo of ruthless revision. The clock circling the hours around that sequence would flex with her life and deadlines.

A practical cycle you can use

Pulling this together, here’s an adaptation of her process — not something she’s published as a formal method, but a reasonable reconstruction from what she’s said across many years:

Capture the emotional image. Find the climax, the relationship turn, or the question that makes the story feel alive to you, even before you know the plot.
Build an emotional map. A playlist, a mood board, whatever helps you feel the tone of the book before it’s structured.
Set destinations, not directions. Identify the major plot points and character arcs. Outline if your project or a publisher requires it — but treat it as provisional.
Draft for skeleton, not sentences. Prioritize plot, character, voice, and pace. Let prose quality and minor fact-checking wait.
Let character psychology overrule the outline. If a planned beat doesn’t fit who your characters have become, change the plan, not the character.
Finish a full draft before judging it. You need the whole skeleton visible before you can diagnose what’s actually wrong with it.
Backfill your research. Verify and enrich details after the scene exists, so research doesn’t interrupt momentum.
Get outside eyes on it. Readers, critique partners, an agent, an editor — whoever is available at your stage.
Turn feedback into a written plan before you touch the manuscript again. Diagnose before you operate.
Cut what you love if it isn’t earning its place. The plotline, the character, the chapter — if its only defense is that you’re attached to it, that’s not a defense.

The lesson that actually matters

It’s easy to read all of this and land on “write faster.” The mechanism that seems to actually drive Maas’s output is the combination of high drafting momentum with very low sentimentality during revision. The speed is what makes it possible to get a whole, diagnosable draft in front of her quickly — the real magic shows up afterward, in her willingness to cut a hundred thousand words, an entire plotline, or a character she liked.

For most writers, the sustainable thing to take from her process is the separation of creative modes: draft with permission to be rough, then revise with a standard that doesn’t care how attached you’ve gotten. That separation seems to be the true source of her power to craft such enthralling stories.

This piece draws on Maas’s public interviews and essays from 2009 through 2026, including her own blog posts on drafting and research, and interviews with Good Reading, A Book and a Latte, Goodreads, Enchanted Inkpot, United By Pop, and Good Morning America. Her more recent public comments focus more on inspiration and story scale than on day-to-day mechanics, so some of the process detail here is best supported for her earlier career and may not describe her current routine exactly.
