Traveling, especially during holiday season, can tax the organized soul. Hordes of people carrying rolling suitcases en masse, fighting across city blocks, onto public transit, through security lines, into terminals and then down the airplane aisle — it’s a battle to retain a state of calm. So the first rule to completing your holiday travels with your sanity intact is ensuring you packed things right. Packing light saves you space and allows you to remain lithe, therefore lowering your stress. But, unfortunately, this means that the luxuries of travel often get swapped with minimalist essentials.
