From who to travel with, to who to trust, travel has taught me a lot, including:
• I am an over-packer. Know it, can't seem to change it.
• Travelling by yourself is great, but having someone to share the moment/debrief/deliberate over where to have dinner with is also great.
• If you're travelling with someone, find someone who likes the same ratio of planning versus spontaneity, and the same ratio of activity versus quiet time, otherwise you will be frustrated and exhausted.
• On any holiday, you will always need quiet time in the afternoon.
