There are as many ways of packing for a trip as there are personalities and people. Everyone has a different style and system of going on vacation and what needs to be packed. The items that come along reflect in a small sense what is most important to that person or on the other hand shows what they can live without.
Whenever I leave home, it strikes me about how simple life really is. You can only fit as much as will fit in a suitcase and a couple other bags, especially if you are flying. To me that emphasizes the saying "you can't take it with you." A vacation is a journey like life is a journey. You realize how little "things" or "stuff" matters when you see how simple life can be without them.
I recently bought a beautiful drawing of a ship, and the quote above is by St Therese, "The world is thy ship and not thy home." It reminds us that we are pilgrims on this earth, on our way to our eternal home. We should make the most of life, not in the sense that we fill every moment with pleasures, but that each moment is lived to the fullest. Like my little red suitcase that has been to England and back, pack light so you have more room for souvenirs. Because even though "you can't take it with you," you want to be able to hold onto a piece of the memory, for that makes up a part of you.
