For everyone who wants to know the internals of the sales game from the view of Sales Engineer or Principal [technical] consultant - that’s the book to read! It’s a manual, the substance over flash, the condensed and the same time very readable material. If you want to improve your sales game beyond the typical sales books, especially if you’re technical resource supporting sales - that’s the one not to be missed. Heaps of good advice, I’d recommend this book to all my peers.
