The question “how do I start writing a book” usually has less to do with typing the first sentence and more to do with the decisions sitting in front of it: what the book actually is, who it is for and how much you need to know before you begin.
This guide walks through that sequence in order, with separate notes for fiction, memoir, business or non-fiction, and children’s books, since the honest answer differs slightly by type.
Should I start with the idea or the title?
Start with the idea. A working title can help you hold the project in mind, but choosing one too early often narrows the book before it exists. Treat any early title as a placeholder you are free to change.
The more useful early task is describing, in a sentence or two, what the book is actually about: not a marketing pitch, just a plain statement you could say to a friend.
What kind of book am I writing?
Fiction, memoir, non-fiction and children’s books each carry different expectations for length, structure and voice. Knowing which one you are writing early saves false starts later.
| Type | What to decide first | Common early question |
|---|---|---|
| Novel | Main character, what they want, what blocks them | Should I plan the plot or discover it as I write? |
| Memoir | Which period or theme, not the whole life | How much do I need to remember before I begin? |
| Business / non-fiction | The reader’s problem and what the book changes | How much research comes before writing? |
| Children’s book | Age range, since it sets length and vocabulary | Do I need an illustrator before I finish the text? |
If you are unsure which category fits, the Book Starting Plan asks a few questions and points you towards a sensible starting shape.
Who is the book for?
"Everyone" is not a reader you can write towards. A specific reader tells you how much to explain, what tone to use and what to leave out.
Example
For example, a novel written for readers of quiet literary fiction reads very differently from one written for readers of fast, plot-driven thrillers, even with a similar premise.
- Fiction: which existing books would sit next to yours on a shelf, and who reads them?
- Memoir: who would recognise something of their own life in this story?
- Business or non-fiction: who has the problem the book addresses, and what do they already know?
- Children’s: which age group, and what do books for that age typically look like?
How do I write the book in one sentence?
Try to compress the book into one or two plain sentences before outlining anything. If you cannot, that is useful information: it usually means the idea is still a subject or a feeling rather than a book with a shape.
Example
For example: "A novel about a woman who returns to her childhood village to clear her late mother’s house and discovers she had a second family." Or: "A practical guide for new managers on running their first year of one-to-one meetings."
This sentence is not a blurb. It is a working compass you can check the book against as you go.
How do I build a rough structure?
Enough structure to know roughly where you are heading, not a finished map. Some writers need a detailed outline; others find it drains the energy out of the writing. Most people sit somewhere in between.
- 1
List the big pieces
For fiction, eight to fifteen key moments. For memoir, the main periods or turning points. For non-fiction, chapter topics in a workable order.
- 2
Note a beginning and a possible ending
You can change the ending later, but having a direction makes the middle easier to write towards.
- 3
Mark what you do not know yet
Leave a note in the outline and keep going rather than stopping to solve it now.
- 4
Stop planning when it starts avoiding the writing
If the plan keeps expanding instead of narrowing, it may have become a way of not starting.
Where should I start writing?
Close to where something starts to change, not at the very beginning of the situation. Many first drafts open with background the writer needed to know but the reader does not yet need. You can move the opening later; it is one of the most commonly revised parts of any manuscript.
If the true opening is unclear, pick the scene, chapter or section you feel most confident about and write that first. A confident start on paper matters more than starting at page one.
How do I create a realistic writing routine?
The most reliable routines are small enough to survive a bad week. Twenty or thirty minutes several times a week will produce a draft; waiting for a free weekend usually will not.
- Pick specific times rather than "whenever I can".
- Set a modest target, in time or words, and count it as done once you hit it.
- Stop mid-scene or mid-point, so the next session has an easy way back in.
- Keep a short running note of where you are and what comes next.
How should I approach the first draft?
Write it to find out what the book is. A first draft is allowed to be uneven, repetitive and wrong in places. Its job is to exist so it can be improved.
Do
- Leave notes like [check date] or [fix later] and keep moving
- Write scenes or chapters out of order if that helps momentum
- Keep everything in one file or folder with regular backups
Avoid
- Rewrite chapter one repeatedly before writing chapter two
- Share every chapter for feedback as you go
- Stop to research every small detail mid-sentence
What if I do not know the ending?
That is common, especially in fiction and memoir. Write towards the ending you currently believe in, and expect it to sharpen or change once you know the material better. Non-fiction is usually more forgiving here, since the "ending" is often the practical conclusion the book has been building towards, which can also shift as chapters take shape.
What do I do after the first few thousand words?
Keep going before judging. It is tempting to reread the opening and start editing once momentum builds, but that is usually the point drafts stall. A better habit is to note concerns in a separate document and address them once there is a complete draft to revise.
If you want a structured way to think about what comes next, I Have a Book Idea. What Do I Do Next? sets out a short worksheet-style process.
Common mistakes
- Researching forever instead of drafting. Research can expand indefinitely. At some point the only way to know what the book still needs is to write towards the gaps.
- Designing a cover before the manuscript exists. It is an enjoyable distraction, but it solves nothing about the actual writing and often happens instead of it.
- Rewriting chapter one endlessly. Polishing the opening repeatedly is one of the most common reasons drafts never reach chapter two.
- Worrying about publishers too soon. Publishing decisions are easier to make with a finished, revised manuscript in hand.
- Comparing a rough draft to published books. Published books have been through multiple rounds of editing. A first draft is not the same kind of object.
Frequently asked questions
Do I need a detailed outline before I start?
No. Some writers work well with detailed outlines, and others find loose ones or none at all more useful. A short list of the main pieces is usually enough to begin.
What if I do not know what type of book I am writing yet?
That is fine to leave open briefly, but try to settle it early, since fiction, memoir, non-fiction and children’s books follow different conventions for length and structure.
How long does it take to write a first draft?
It varies with the length of the book, time available and research needed. A steady routine of a few hours a week can produce a full-length draft over several months to a year.
Can I start writing in the middle of the book?
Yes. Many writers draft the scenes or sections they feel surest of first and fill in around them afterwards.
