If you have ever seen a professional keynote speaker come on stage and deliver an entire hour-long presentation without any notes, he/she probably used the Palace (or Room) technique. This technique is similar to the Stacking Technique, but instead of memorizing the images in sequential order with actions connecting them, the images are placed within a location that you know extremely well. So, just like in the Stacking Technique, you create an image for each main point in your presentation.
Next, pick a location you can easily remember in great detail. It could be your house, office, or even the meeting room or banquet hall if you want. Then create a logical ‘route,’ based on which rooms or objects that you see first. For example, when you open the front door of your home, what is the first room that you enter?
After deciding on a route, imagine taking that route and focusing on the rooms or items AND the order that you see them. Using my home as an example, when I enter through the front door, I'm standing in the formal living room. The first object that I see is the sofa to my left. This is where my dog sleepily wags her tail when I first enter. To my right is my wife's office. Straight ahead is the formal dining area with a big table that is only used when my family visits on a holiday. Next is the smaller living area where the TV and comfy sofas are. Finally is the kitchen with the island in the middle.
Since I know this route well, I can easily insert the images that we prepared in the Stacking Section. Instead of seeing my dog on the formal sofa, there is an oversized pair of scissors cutting a price-tag. Onto my wife's desk is the disgruntled golfer. seated at the head of the formal dining table is my employee with her arms stretched across the table to shake hands with a happy customer. If I had a fourth point, it would be watching TV. The fifth point would be on the kitchen island.
