Rick Steves: "Pick two"

“You’ll never meet a traveler who, after five trips, brags, “Every year I pack heavier.” The measure of a good traveler is how light he or she travels. You can’t travel heavy, happy, and cheap. Pick two.” - from Newsday
 
Some highlights:
 

• “Whether you’re traveling for three weeks or three months, you pack exactly the same.”
  
• “Pack for the best scenario — not the worst. You can buy yourself out of any little jams as you go.”
• “The bulk of your luggage is clothing. Minimize by bringing less and washing more often. Every few nights you’ll spend 10 minutes doing a little wash.”
