Query: This book has topped Strategic Selling and Solution Selling

George Ludwig grasps concepts that seem to have eluded many of the leading thinkers in sales and he debunks many of the myths that revolve around so-called "strategic selling". His original research that uncovered "the seven powers" of the world's greatest salespeople, which are really "best-of-breed practices," is right on the money. This might be the first sales book you could actually hand to your buyer and say "Here's how I'd like to proceed with you," because of the integrity and trust woven into the Power Selling approach. I literally read the entire book cover-to-cover in one sitting, and as of this writing I'm reading it a second time. And Ludwig's on-line assessment tool is a great addition to the book. The book has definitely helped my air charter business grow to the next level and it's the best overall book on selling strategy I've ever read--and I think I've read most of them.
