I have packed for two-person trips, one-week trips, and one trip so long I forgot what my own couch looked like. I started packing a curated travel system. The system is the only reason I still have a marriage and a functioning nervous system. My husband will tell you I over-research everything, from the right headphones to the right way to fold a cardigan. All of it earned its spot the hard way, usually while I was tired, annoyed, or standing in an airport pretending both of those things weren’t true.
