By now you have two core storage strategies: the Story Chain (Day 3), one item linked directly to the next, and the Memory Palace (Days 5-6), items pinned to fixed locations. They solve the same basic problem differently, and knowing when to reach for which one will save you time.
Use the Chain when the list is short, disposable, and order-only matters, a quick errand list, a short sequence of steps. It’s fast to set up and you don’t need to reuse it later.
Use the Palace when you need to keep information around long-term, jump into the middle of the list without walking the whole thing, or store several separate lists without them tangling together. A chain breaks if you forget one link in the middle, a palace doesn’t, each loci stands on its own.
