Have you ever actually analyzed how you spend your time at work? For example, how much of your day is spent answering e-mail, participating in meetings and conference calls, proposing big ideas, or working on something tangible?

According to bestselling business author Dan Pink, U.S. workers spend about 40 percent of their time at work engaged in “non-sales selling.”

Don’t believe it? In his latest book, “To Sell is Human: The Surprising Truth About Moving Others,” Pink states that “like it or not, we’re all in sales now.” Pink contends that whether we are employees pitching colleagues on a new idea, entrepreneurs enticing funders to invest, or parents and teachers cajoling children to study, we spend a significant portion of our days trying to move others.

Pink used Qualtrics Research Suite to conduct his “What Do You Do At Work?” research for this book. He talks about his book and the do-it-yourself research process for writers in a recent 12-minute MediaBistro GalleyCat interview – here are a few excerpts:

“There are so many incredible, powerful tools out there that allow writers to do the kind of quantitative research that would have been absolutely cost prohibitive a few years ago. For a tiny fraction of what it would have cost 10 years ago, I could get some systematic, quantitative research to see if these claims that I was making actually made any sense.

“I’m pretty good at the quantitative stuff, but I’m not an expert. But I was able to fashion a pretty sophisticated survey and go out using social media to generate a large, valid sample.

“The software is really easy to use and Qualtrics has some serious experts who will help you design your surveys so you avoid serious mistakes.”

If you didn’t already know, Dan Pink has authored several other provocative books about the changing world of work, including the The New York Times bestsellers “A Whole New Mind” and “Drive”. In 2011, Thinkers50 ranked him one of the 50 most influential business thinkers in the world.
