Good packing isn't about fitting more in. It's about carrying less and finding things fast. These habits work for a weekend in Lahore or two weeks abroad.
Lay out what you'll wear each day, then pack only that. Pick pieces that mix with each other so a few items make several outfits.
Last-minute packing is when chargers and passports get forgotten. Packing the day before gives you a night to remember what's missing.
Group things by type: clothes, toiletries, cables. You can pull out one pouch instead of unpacking the whole bag, and security checks go faster.
Passport, phone, wallet and boarding pass belong in a small bag you never put down. A crossbody sling keeps them close and hands-free.
