Keep all your things visible in a hotel room, not in drawers, and all gathered into one spot. That way you’ll never leave anything behind. If you need to have something like a charger off to the side, place a couple of other large items next to it, because you are less likely to leave 3 items behind than just one.
人很容易被自己的利益驱使,仅仅让他看到正确是不够的,还必须让他感受到它。
