I had my passport, my insurance, my hire agreement and my prescription list in four different places, and I spent the first afternoon of a two-week holiday finding out which pocket each was in. One wallet with labelled sleeves fixed a problem I did not know was a problem until the third time somebody asked me for a piece of paper.

The second thing: I packed for two weeks and wore the same four things. Two merino shirts did the work of six cotton ones and took up a third of the space. Nobody tells you that the correct amount of clothing for a fortnight is roughly four days' worth, because it sounds like a trick. It is not a trick.
