Make a map of a place you know well—but haven’t been to in a while—using only your memory. Perhaps it’s your neighborhood growing up; or Barcelona, Spain; or your grandmother's cabin. Maybe it’s the house or apartment you grew up in.
Include details that are uniquely yours—"the corner where Sam showed me a knife" or "it always smelled funny here."
Include little notes and other remembrances on your map. Spend some time in that space mentally and try to capture even more details.
Do you remember more than you thought you could?
