I've always been told this by fellow travellers. They say you'll reach a stage in travelling when like friends, you'll count the number of possessions you truly treasure on one hand.
I'm not quite there yet...I still get excited when I travel and buy lots of little things to remind me of the places I've been and the things I've seen.
I'm also wholly addicted to books. I buy lots of them. Lots and lots of them. They line the shelves in my room and I never tire of reading them. Whatever you do, don't ask me to pick a favourite book!
What about you? Can you fit your life in a rucksack? Can you count your most treasured possessions on one hand?
