Lost in your watery reverie, some might unkindly call you irresponsible. You're a dreamer. You have more important (or at least more interesting) things to think about than the practical nitty-gritties of daily life!
Turn what some might consider a fault into a new way to travel. If you're always forgetting half the things you meant to pack - dressy clothes, sunscreen, raincoat? - take the opportunity to explore and mingle with the locals at your destination.
There's a better than even chance that they wear clothes, and that the shops will have everything you need. You'll meet people, figure out the currency, and have some cool, unique stuff to show off when you get home!
