LEAVE THE CONTRABAND
It is uber-helpful to remember the exact positioning of each item in your luggage, to save vital time in drenching moments. It is an even more important, complimentary wont, to know the exact contents of the bag. This is crucial, for fast packing/unpacking, for example, not to leave things accidentally in hostels. If the habit of keeping track of possessions is not developed, it is also quite easy to bring prohibited items in the carry-on into the airport.
