Say you want to remember to take a particular bag with you when you leave. Close your eyes for 5 seconds and imagine something outrageous, surreal, balls out crazy. Only takes 5 seconds, but the crazier the image you make up the better.
For this one I might imagine my postman or UPS standing there when I open my door, with the bag covering his head. Or I might imagine that bag as a giant bag full of rabid weasels blocking the door.
You might not even see the image again, but you will remember the bag. Shit’s like magic.
