Communicate Better, Sell More
Any salesperson worth his or her commission knows that communication is everything, and that mastery of communication only leads to mastery of your business. Ryan T. Sauers, president and owner of Sauers Consulting Strategies, recently published a book called "Everyone is in Sales," a book dedicated to the study of communication, breaking it down and laying out the different ways people listen, talk and otherwise drive their communicative behaviors. While not specifically written for salespeople, the book's exploration and framing of different parts of communication is useful for all facets of business, from sales to management to marketing.
I've seen Ryan give educational seminars and have previously interviewed him for sales-advice articles I've written. Practical, open-minded and able to mix academics and years of personal experience well, he is one of the best business experts I've worked with, and I have spoken with my fair share.
