A long time ago, it didn't matter how many suitcases you brought along on your trip. Sizes and weight weren't much of a concern, either. But in this modern era of security checks and surcharges, it's best to plan a minimalist approach to luggage, bringing only what you really need (or less).

In the article, 15 Packing Secrets From a Professional Traveler by Nora Dunn (not the former SNL performer), you'll find some great tips on packing lightly from someone who literally lives out of a suitcase and travels the world full-time.
