Are you dreaming of writing a book sometime in the future? Could 2016 be the year you take it from thought to action?

A book is the new fastest way to get your message out, share value about your company, and give others the gift of learning what you know. You don't have to be Elon Musk, Sheryl Sandberg, or Marshall Goldsmith to put pen to paper.

I just wrote a book in four months, and you could do the same. When Wiley asked me to write my new book, Thoughtfully Ruthless: The Key to Exponential Growth, so that it could be on shelves by May 2016, at first I froze. I had no idea if I could write a book in just 16 weeks. I spoke with my mentor and a few other advisers, who all told me that it was absolutely possible, so I said yes.

Executives and entrepreneurs I work with often say to me, "Val, I could write a book with the stories I could tell." They are great storytellers, and they have valuable lessons they can share with others, but then they tell me they could never write a book because they don't have the time. Fellow consultants and speakers often share that they have a book idea they have been considering for years. I compiled this guide to help you write your brilliant book fast:

1. Learn from the masters

You would never train for a marathon with a coach who ran sprints, so don't listen to advice from anyone who hasn't written a book. My mentor, the rock star of consulting himself, Alan Weiss, has written more than 60 books, so his guidance has been priceless.

2. Know why

Before you start writing, you need to know why you want to write a book. As a leadership and innovation expert, my clients kept telling me that I had to write a book to share all of my ideas and stories with a broader audience. I wrote my book to help executives and entrepreneurs rapidly grow their business, magically create more time, and boost their energy.

3. Understand the business of books

You made a plan for your business; your book needs one too. If you're self-publishing, you can jump in and simply write your book. If you want to use a traditional publisher, I highly recommend reading Jeff Herman's Write the Perfect Book Proposal, which provides the ideal format and practical advice for pitching. 

4. Nobody can read the book that is still in your head

Eating ice cream can give you brain freeze, but productivity brain freeze is worse; it suspends you into a period of inaction that is as painful as it is inefficient. Productivity brain freeze may stop you from putting pen to paper. Whenever I had a slow writing session, it was because I had let my mind wander to questioning if it was the right time to write, if I needed to prioritize other projects, or if my examples were the right ones, when I simply needed to ignore my brain freeze and just write.

5. Use an air-gapped PC

In an episode of The Newsroom, in which secret government documents were being leaked to appear on the news show, I learned that an air-gapped PC was one that had never been connected to the internet. At that moment, I knew that was precisely what I needed to increase my writing productivity. I wrote my book on a laptop that didn't connect to the internet and could not distract me.

6. Find your perfectly productive place

I love writing on the grounds of the Huntington Library, underneath the giant palm tree at the bottom of my garden, and on airplanes. They are my perfectly productive places where I have my best ideas. I don't get distracted, and write the most prolifically. Where are you the most efficient?

7. Practice your stories

Everyone has his or her favorite dinner party stories, those tried-and-tested tales that you know will get a reaction from your audience. When I speak at conferences, I pay attention likewise to what gets the strongest responses. Test out your stories for your book when you talk to your employees and investors. Note which get the best reactions and include them in your book.

If you are deliberate about where you spend your time and energy, doing more can actually increase your productivity. While writing my first book manuscript, I had an idea for my second book, Innovation Trifecta: How to Catapult Innovation by Creating a Symbiotic Relationship Between Creative, Business, and Technical Teams. Writing the proposal simultaneously with my first book sped up my writing productivity and gave me more ideas for both books.

This time next year you could see your book on bookshelves around the world. The question is, do you have the thoughtful ruthlessness to do it?
