Easily one of the most stressful parts of traveling, packing should be efficient and full of necessities. Work to eliminate the "extra" and only leave with what you know you'll wear, use, and need. By creating lists, knowing your destination's climate, and understanding that you don't need that fourth pair of shoes, you'll quickly learn to pack with purpose and make sure that you'll have room for those souvenirs that you want to come home with. It will also help prevent forgetting your "must haves" and returning with a bag of unworn clothes.
