I would highly recommend "Sales EQ" by Jeb Blount as a first sales book - https://www.amazon.com/dp/B06XFBMZVC/ https://www.amazon.com/dp/B06XFBMZVC/. Does a very god job of outlining the psychology of selling, the psychology of buying, and what needs to go into a successful sales process (without laying out a prescriptive program). Conversational writing style, very rich in information. It will be very useful in improving "non-sales" selling aka presenting, convincing colleagues of things, etc Though things like New Strategic Sales and Spin Selling are useful, they are not good beginner books - they are technical approaches to developing enterprise sales process, and primarily targeted at professionals in sales management. As a less than exact analogy, Sales EQ is much more like SICP, while Spin selling is like an O'Reilly language reference. I know non-programmers that have gotten a lot out of SICP as the only cs book they have read
