Plan your route (the same one you always take). First, arrive at the door. Now, step through. Imagine yourself walking through your palace. Let your muscle memory be your guide as you navigate one room at a time. To make sure you really know it, why not try walking your route backwards? Then, once you have the architecture of your palace vivid in your mind, you can begin to insert the mental images of your grocery list into its spaces. Picture: a mandarin bouncing down your carpeted stairs or a toothpaste tube oozing its stripes out on your bathmat. When you wish to recall your grocery list, just place yourself in your palace and walk along the path to recover the things you left along the way. -- Asia Jong
