Pack Half the Clothes and Twice the Money
We don't know who said it first, but some of the best packing advice we've ever received is this:
Lay out the clothing and cash you plan to bring on your trip. Now pack just half of the clothes and double the money. The point is that people often overpack and regret bringing certain items of clothing, but no one ever regrets bringing extra money. You really won't need as many clothes as you think!
