ToggleWhy 90 Days Works for Writers
Writing a book is often seen as a long-term commitment, and that belief alone can scare people away. But 90 days creates a focused deadline with enough breathing room to make real progress. It’s the sweet spot between a sprint and a marathon. 🏃♀️📆
Here’s why the 90-day timeframe is ideal:
- ✅ It’s long enough to build consistent habits.
- 🚀 It creates a sense of urgency without chaos.
- ❌ It pushes you to silence perfectionism.
- 🧭 It keeps you accountable and results-focused.
Many bestselling authors use structured writing schedules. Ninety days is a common format among those who’ve learned how to balance creativity with discipline.
Is It Possible to Write a Full Book in 90 Days?
Absolutely—if you approach it with intention.
Let’s break it down:
Say you want to write a 60,000-word book. That’s a solid length for most nonfiction books and novels. To complete that in 90 days, you need to write roughly:
667 words per day
That’s about two pages of content—a manageable daily target, even for those with full-time jobs or busy families. And remember, not every day has to be perfect. Some days you’ll write more. Some days less. The goal is progress, not perfection.
The 90-Day Writing Formula: A 3-Part Journey
Your 90-day writing process can be broken into three clear phases—each about a month long.
Phase 1: Pre-Writing & Planning (Days 1–30)
This first stretch is all about laying the groundwork.
🧠 What you’ll do:
- Define your core book idea
- Get clear on your target audience
- Outline the chapters and themes
- Break down your word count goals
- Lock in a daily or weekly writing schedule
This is also the phase for research. If you’re writing nonfiction, gather data and references. If it’s fiction, this is your time to flesh out characters and plotlines. 🕵️♂️📚
🎯 Your goal: clarity and a clear roadmap.
Phase 2: Writing the Draft (Days 31–60)
This is where the magic happens—putting words on the page.
🛠️ How to stay on track:
- Hit your daily writing target (around 667–800 words)
- Write in sprints to maintain momentum 🏃♂️💨
- Avoid editing—just write!
- Use writing tools that help you focus
- Make time for writing like it’s a meeting
Remember: this draft is not the final version. Your goal is to finish the manuscript, not to make it perfect.
Phase 3: Revisions & Refinement (Days 61–90)
Now, you shape your raw material into something publishable. 🎨📝
What to focus on:
- Read through your entire manuscript 🧐
- Fix plot holes, improve flow, remove fluff
- Polish dialogue or transitions
- Cut down repetition
- Strengthen your book’s structure
If possible, get feedback from beta readers or critique partners. Then make final improvements before editing and proofreading. ✅🔍
