How to write a memoir: Start with the theme, then build the story

If an autobiography tells the story of your whole life, a memoir zooms in on a specific piece of it. A memoir is a focused narrative built around a central theme or question, often rooted in transformation, struggle, identity, or insight. It’s not about everything that’s ever happened to you—it’s about what happened and why it matters.

In my last blog post, we talked about how the basic steps of the novel writing process can be used to write a full autobiography. The same holds true for memoir—but with one crucial shift. With memoir, the first step isn’t structure. It’s theme. Let’s walk through how to find your theme and shape your memoir around it—one notecard at a time.

Start with stories, not structure

You don’t need a perfect plan to begin. If you already know what your memoir will focus on—say, your years living abroad, recovering from an illness, or coming of age in a particular subculture—great. If not, the best place to start is story brainstorming.

Grab a stack of good, old-fashioned note cards (or a digital equivalent). On each one, jot down a short description of a personal story or memory that feels meaningful. These can be funny, sad, confusing, or pivotal. Don’t worry yet about whether they “fit.” The idea is to build a pile of scenes and moments that reflect your lived experience.

Let the theme reveal itself

As your stack of stories grows, patterns will start to emerge. You may notice that many cards touch on a shared emotional thread: shame, resilience, reinvention, freedom, grief, identity, faith. That’s your theme in the making.

If you already have a theme in mind, use it to help sort your cards. If not, let the stories speak first. Memoir often works like this: you think you’re writing about a job you had, but then you realize you’re really writing about your father. Or you think it’s about a breakup, and it becomes about self-worth. Don’t force the theme too soon. Instead, allow it to surface in its own time.

Discard the stories that don’t fit (for now)

Once your theme becomes clear, go back through your stack of note cards. Set aside any stories that don’t serve the focus of this particular memoir. That doesn’t mean they aren’t valuable—they might belong in a future memoir. But for this book, clarity is key. A focused memoir resonates more deeply than one that tries to cover too much ground.

Shape your beginning, middle, and end

Now that you know your theme and which stories support it, start thinking about narrative structure. Memoirs, like novels, benefit from a sense of momentum.

Ask yourself:

• Which story marks the real beginning of this journey?
• What turning points changed me?
• Where does this story naturally end?

Your structure might be chronological, fragmented, cyclical, or experimental. There’s no one right way—but readers do appreciate a clear throughline. Your notecards can now become chapters. Lay them out on a table or wall and start rearranging. You’re not just telling what happened—you’re building a narrative.

Write and keep discovering

Start drafting your chapters—but don’t worry if your theme evolves. Memoir is as much about discovery as it is about documentation. Sometimes you won’t know what a chapter is really about until you’ve written it.

Keep your discarded cards nearby. You might find a place for one after all, or it may inspire something new.

Final thoughts

Writing a memoir isn’t about capturing everything—it’s about shining a light on something specific and true. Start with your stories. Allow the theme to emerge. And build your memoir from there, one honest chapter at a time.
