The secret to simplifying travel packing is the "capsule wardrobe" method and the use of packing cubes. Start by choosing a single color palette so that every top matches every bottom, allowing you to create multiple outfits from just a few pieces. Aim for the "5-4-3-2-1" rule: 5 sets of socks/underwear, 4 tops, 3 bottoms, 2 pairs of shoes, and 1 hat/accessory. Packing cubes are essential as they compress your clothes and keep your suitcase organized, effectively acting as drawers in your bag. To save space, roll your clothes instead of folding them, which also helps prevent wrinkles. Another simplification tip is to "decant" your toiletries into reusable 100ml containers or switch to solid bars for shampoo and soap to eliminate the risk of leaks and clear security faster. Finally, always pack your heaviest items near the wheels of your suitcase to keep it balanced and easier to maneuver through terminals, and keep a "survival kit" with essentials like chargers and meds in your personal item.
