I think I am probably the most unexperience traveler here, when we went anywhere, we moved with all of our things

How do you guys pack lightly for a trip? I really thought I saw somewhere that listed each item so you could mix and match with very little in a suitcase. Yes, I'm a nerd and a neurotic list maker!
My husband is a packhorse, so I don't want to bring much at all.
Thanks!!
