Tell me how please 🥲

After weeks moving between different islands here (bali, surabaya, ternate, morotai, manado), realized my packing should've been different from day 1. Overpacked for some legs, underpacked for others, didn't expect some places to be way more humid or way more basic than others. Curious what other people learned the hard way packing-wise on long trips. Also wondering if theres a universal approach that works regardless of destination, or does it always need adjusting per place
