80/20 Sales and Marketing: The Definitive Guide to Working Less and Making More
Perry Marshall · ★★★☆☆ · 230 pages · 2013
Sort of a continuation of the 80/20 principle from Koch and how to use it in modern marketing and sales. Segmentation, have someone else do the 80 percent where you are not delivering value, learn to give up 80/20 at times or you will be seen as a grinch. All good advice
