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.
Science is not just a collection of facts; it's a way of thinking.
One is not struck by the truth until prompted quite accidentally by some external event.
