Pat Helmers, sales guru extraordinaire, trainer, and podcast host, interviewed me recently about using memory to improve sales. We also discussed my new book, The Hack-Proof Password System.
Pat admitted he uses a software solution for managing his passwords and put me to the test to convince him that my techniques were easy and effective. I think I did, but listen for yourself, especially if you have doubts about whether you should use your mind as the ultimate hack-proof password storage!
