Packing my bag for a longer journey is always something special, as I know I will be using those clothes and that stuff over and over again… It is also difficult as it comes with two rules: 1) pack everything important, but 2) not too much and not too heavy! As some flight companies have baggage restriction to 15 kg, I want that my backpack weighs max. 15 kg plus my important electronics and adapter in my hand luggage (but I can fit it into my backpack as well so that I can walk around with just one big luggage if I need to). My backpack has space for 55 +15 kg and weighs itself already 4 kg. At the airport my backpack weighed 14,2 kg. Yeahhh, I made it! ^^ I highly recommend to bring your own airport backpack bag (into which you can wrap your backpack) as your backpack can get damaged so much by the conveyor belt.
