How long did it take these authors to write their books?

Daniel Pink

Daniel Pink

Author of seven books on motivation, timing, sales, and regret

NYT bestselling author

Why themWrote speeches and articles before seven books.

Daniel’s advice: About 70,000 words at 500 a day: half a year of drafting, and the rest doubles it.

For me, a book is about 70,000 words. I write 500 words a day, six days a week, so that's roughly half a year of actual drafting. The rest, research, revision, and listening to my wife read every chapter aloud, easily doubles it.

Charles Duhigg

Charles Duhigg

Pulitzer Prize-winning journalist and author of The Power of Habit and Supercommunicators

Pulitzer Prize-winning journalist

Why themTurned years of reporting into bestselling books.

Charles’s advice: About three years per book; the writing is the last nine months.

For me, a book takes about three years from the first real reporting to the final manuscript, though the actual writing is usually the last nine months or so. The rest is reading studies, interviewing people, and figuring out what the book is actually about, which always changes.

Brendon Burchard

Brendon Burchard

High performance coach and author of The Motivation Manifesto

3-time NYT bestselling author

Why themSelf-published his first book after agents passed.

Brendon’s advice: 18 days for one book, three years for another. Set a 90-day sprint.

I’ve done one in 18 days at my mom’s sewing table and I’ve had another grind for three years. For me it takes the time I allow, so I make it a 90-day sprint and start by writing the first page today.

Guy Kawasaki

Chief evangelist of Canva and author of APE: Author, Publisher, Entrepreneur

Former Apple chief evangelist

Why themSelf-published, then wrote the guide to doing it.

Guy’s advice: Six to twelve months at the keyboard, after a lifetime of material.

I tell people it takes thirty years to write a book: six to twelve months at the keyboard, and the rest is every lesson, failure, and insight that made you worth reading. The typing part is not the hard part.

Nir Eyal

Nir Eyal

Author of Hooked and Indistractable and the writer behind NirAndFar

NYT bestselling author

Why themHis agent found him through his blog.

Nir’s advice: Hooked took about five years; protected writing time finishes the draft.

My first book, Hooked, took about five years from research to publication, and Indistractable came together after I made a $10,000 price pact with a friend to finish the draft by January 1st. The real answer, though, is however long it takes you to protect the time: I timeboxed two hours of distraction-free writing six days a week until the manuscript was done.

Robert Cialdini

Robert Cialdini

Founder of the Cialdini Institute; has spent his career researching persuasion

NYT bestselling author

Why themRewrote Influence until it spoke to general readers.

Robert’s advice: He planned one sabbatical year for Pre-Suasion, and it came in several years late.

I once planned to write Pre-Suasion during a single sabbatical year with an uncluttered calendar, and it still came in several years late. The real answer is not how long the writing takes; it's how long it takes to live with the idea until the book is finally ready to let go.
