I use the same principles I use for ultralight hiking: -Take only what you will actually use. "What-ifs" are heavy. We pack to lessen our fears and knowledge is the answer---and light. - Assemble a closely integrated layering system of clothing and color coordinate so it's all interchangeable. You can always buy more if needed. - Use the "three method" for clothing: one worn, one dirty, ine clean. Use items you can hand wash and line dry overnight. You can travel for months with the same items it takes for a week. Laundry is the difference. On a recent three week trip I used a laund once and an Airbnb had a washer which I used once. Everything else was hand wash and line dry. If the weather is good, walking sandals are great and no socks to wash! - Get a Kindle to eliminate book weight. I've gone to a small tablet to replace a laptop and that fills the e-reader niche too. Be careful on electronics -- they can snowball with all the cables and chargers, powerbanks, etc. I have a 4 port usb charger that takes care of everything for two people and needs just one outlet. It is 100~240 volt so it just needs an adapter for the local outlet type. - I carry my electronics, books and TSA liquids in my carry on "personal" bag which goes under the seat. Where they might weigh your larger overhead carry on, I have never had my personal bag weighed (yet). All said and done, a 10kg limit is a good thing for me as I use a backpack and who wants to haul more than that anyway! It's not hard to do. When hiking, I am carrying shelter, sleeping gear, cooking gear, essentials, food and water and my 3 day limit is 21 pounds, so taking just clothing, toiletries and electronics at 22 pounds is much easier.
