“What we need to do is treat some of our thoughts like door to door salesmen. If someone comes to your door and asks if he can come inside and throw some dirt on your floor to demonstrate his vaccuum cleaner - you would probably tell him “No thanks! See you later!” And yet - if a friend stopped by with a meatloaf and wanted to visit - we’d say “Come on in!” We need to stop being PASSIVE about what thoughts can take residence in our head.”
