Travel Essentials: How to Travel Simply
My husband can tell you about the days early in our marriage when we would go visit family in Canada and I would have a suitcase and a few additional bags. I made sure to pack everything I thought I would need. Then I would pack additional clothes and supplies for things I may not need now, but in case anything changed, I was prepared.
Fast forward several years. My husband and I were leaving the continent to go backpacking through India. I purchased the smallest hiking backpack, known as a day pack. I planned to only pack what I could carry easily through India. If you can imagine, my pack list shrunk by over 90%. I did so much research for this trip that I had hoped to pack exactly what was needed. Between that trip to India and many future trips, I feel I have packing down to a science (even if I still wait until the last minute to pack).

Having been to 24 countries now, I now can boldly swap out my “must pack” based on the country I am traveling to. To keep things simple, here is a list of “must have's” I would use for any country I would visit. Some of these "must have's” are readily available at a store in the country you are visiting. However, if you are traveling to remote locations in Thailand, backpacking in the countryside of Spain, hiking through the jungles of Belize, I would recommend packing these instead of rolling the dice of how to find them.
