How a Murder Mystery Writer Mastered the Art of Productive Time Use

The Late-Night Writing Habit That Built a Legacy

When Keigo Higashino passed away in July 2026, he left behind 106 novels. That's not just a number—it's a testament to what happens when you treat time like a craft. As a young engineer at an auto parts company, Higashino didn't have a writing studio or a publisher's deadline. He had a job, a commute, and an evening. And he used that evening relentlessly.

I think about that when I'm tempted to say I don't have time. He didn't either. But he made a habit of writing after work, for hours, before calling it a night. That's not talent. That's structure.

The Power of a Routine That Outlasts Motivation

Higashino's early career was a lesson in patience. His first novel, Magic Ball, made it to the finals of the Edogawa Rampo Prize but lost. He didn't quit. He wrote another one, After School, and won the next year. That's a pattern: treat every rejection as a data point, not a verdict.

For anyone trying to write a book, start a side project, or learn a skill, the takeaway is simple: show up at the same time every day, even when it feels pointless. Routine beats inspiration because routine doesn't care about your mood.

Time Blocking: The Hidden Structure in His Novels

If you read Higashino closely, you'll notice his plots are built like a schedule. He sets a timeline, drops clues at precise intervals, and resolves everything by the final chapter. That's not accidental. He once mentioned mapping out his stories before writing, which is essentially time blocking for narrative.

You can borrow that for your own life. Block out an hour for deep work, another for meetings, another for rest. When you assign a time slot to a task, it becomes a commitment, not a wish.

From Engineer to Full-Time Writer: Managing Transitions

Higashino didn't quit his day job until he won the prize. That's a smart transition strategy. He kept his income stable while testing his writing on the side. Only when the side project became sustainable did he go all in.

If you're dreaming of a career change, don't jump off a cliff. Build a bridge. Use your evenings and weekends to test the waters. Keep your safety net until you have real evidence that the new path can hold you.

The 80/20 Rule in a 106-Book Career

Not every Higashino novel is a masterpiece. Some are average, some are forgettable. But he kept producing because he knew that quantity leads to quality. He applied the 80/20 rule: focus on the few things that move the needle, and let the rest be practice.

For your own productivity, ask: What 20% of my tasks generate 80% of my results? Do that first. Defer or delete the rest.

Recharging Creativity: The Role of Walks and Observation

Higashino was known for taking long walks and observing people. He believed that a writer's job is to notice the details others miss. That's also a productivity hack. Stepping away from your desk isn't wasting time—it's refueling.

Schedule breaks like you schedule meetings. Go for a walk, listen to music, or just stare out the window. Your brain needs idle time to connect dots. Don't feel guilty about it.

What We Can Learn from His Final Year

Even as he battled illness, Higashino finished his final novel, Eternal Memories. That kind of dedication isn't about willpower. It's about having a system that keeps you moving even when you don't feel like it.

We won't all write 106 books, but we can all build a time management system that respects our energy and priorities. Start small: pick one habit, schedule it, and stick with it for 30 days. That's how a legacy gets built.
