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.
And what I noted, since the really big ideas carry 95 percent of the freight, it wasn’t at all that hard for me to pick up all the big ideas and all the big disciplines and make them a standard part of my mental routines. Once you have the ideas, of course, they are no good if you don’t practice. You don’t practice, you lose it.
