According to the U.S. Bureau of Labor Statistics, one in nine Americans works in sales. More than fifteen million people earn their keep by convincing someone else to make a purchase.

But dig deeper and a startling truth emerges: Yes, one in nine Americans works in sales—but so do the other eight out of nine. Whether we’re entrepreneurs persuading funders, employees pitching colleagues, or parents and teachers cajoling kids, we spend our days trying to move others. Today, like it or not, we’re all in sales. Or as Daniel H. Pink puts it, everyone is in the “moving business.”
