To make the place feel like your own, do something illogical to the place just because you decide to. You might move the furniture into odd positions and leave it there or put it back again, or sprinkle baking soda all over the floor and then vacuum it up again, or arrange some small objects in a pattern as decoration, or something. To feel as if you’re in charge and can do whatever you want, and that the place reflects your own individual creative thoughts.
