Like it or not, we are all in the sales business. If we’re not actively selling a product, we’re selling ourselves. So much in life, from our careers to our relationships, all depends on our ability to sell.

And it’s a skill we all need to master, according to bestselling author and former Al Gore speechwriter Daniel Pink.

Pink has been called one of 50 most influential business thinkers in world, and he’s the author of 5 books, including the bestsellers “Drive” and “A Whole New Mind.” In his new book is called “To Sell is Human,” Pink looks at the art and science of selling.

Pink says these days, it’s the job of 1 in 9 people in the workforce to sell something, but the other eight in nine are in sales, too. Even if they’re not selling a specific product, they’re still spending a lot of time persuading, cajoling and influencing their clients, their co-workers, their bosses or employees.

It used to be that sellers always had more information than buyers, but now the information advantage has disappeared, Pink says. He says sales is much more open and transparent now and as a result, you have to do it in some fundamentally different, and more human way.
