Travelling Light
Travelling light is simply a better, more hassle-free way to go. You have more time, because packing takes little. You waste less energy hauling stuff. You know what you have, and where everything is (as you pack your bag the same way every time). We've all seen those hapless folks at the airport, with too much baggage and panicked expressions, worried that they have lost track of something, or left something behind. Foreign travel in particular can be challenging because it is unfamiliar and unpredictable, but the one-bag traveller copes by operating from a solid, familiar foundation, with fewer unnecessary things to worry about.

Don't Leave Home Without It
When traveling internationally, always keep a copy of your passport for backup purposes. Keep your original passport (together with your families) in one place at all times (whether it's in a purse or carry on). Once in the hotel, (most international hotels have safes for this very reason) put your passport(s) in the safe for secure holding. it is the safest way to keep and maintain your "identity" while abroad.
