Packing light is a talent. You have to know what you want and need to bring at such a small space. It’s a compromise for some things but personally I’d compromise those just to have the convenience of carrying light baggage or having cheaper fares. TIP: you’ll be carrying less on your flight out than in. Most travellers will be buying souvenirs and goodies on their way home which means additional weight to carry on. So it’s efficient to be packing light. For longer travels consider laundry services in your hotels or wearing your newly bought shirt for yourself. Just a note on laundry services, avoid those clothing that bleeds color to whites, etc. or else you’ll be left with aweful tints on your shirt on your way up the Petronas tower.
