When buying a garden hose， an extension cord， or a ladder， get one substantially longer than you think you need. It’ll be the right size.
When you arrive at your room in a hotel， locate the emergency exits. It only takes a minute.
What you actually pay for something is at least twice the listed price because of the energy， time， money needed to set it up， learn， maintain， repair， and dispose of at the end. Not all prices appear on labels. Actual costs are 2x listed prices.
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.
