Since I travel so much, I don't have very many things that I NEED in my life, I guess I would say my ipad is the most important thing; it has photos, contact information for my friends and family and it's what I use to stay in touch with people I love while we're apart. Plus the games on it have provided me with hours of entertainment on long trips.
But I don't think any "thing" is as important as my husband and our shared love of adventure. I hope we both never lose the ability or the desire to try new things, visit new places, meet new people and expand our minds through experience. I think having the courage to step out of my comfort zones has changed my life every day.
This is a nice, thought-provoking question. It reminded me just how much I have to be thankful for, so much in life is precious!
