Perry Marshall is best known as the web's foremost authority on pay-per-click marketing, and the author of The Definitive Guide to Google AdWords. But his latest book, which took 10 years of research to complete, is 80/20 Sales and Marketing. Perry says the greatest secret to success is MASTERY of the 80/20 principle, because when you know how to walk into any situation and identify the 80/20’s, you can solve almost ANY money problem... any traffic problem... any conversion problem.

He says most people THINK they understand 80/20, but not one person in 1,000 actually does. And knowing the 80/20 principle allows you to fix your own business, or fix other peoples’ businesses. It has levers within levers, so that 1% changes can trigger 50% profits. If you’re tired of trying stuff, trying stuff, trying stuff and never getting off the treadmill, this could be your ticket to success.
