Hard to say. I didn't travel much when I was young so after I graduated, it was as if everything was a new opportunity. The first country that I visited which was vastly different from my own was Malaysia, so that country will always have special memories for me.
When I was teaching in the US, I had the idea to travel during the summer breaks. But I realized I'd only be living for those times when I'd get to travel. I was then introduced to the idea of teaching English abroad. Instead of waiting to travel, I'd be living elsewhere constantly. I loved the opportunity of living in other countries and actually getting a closer look at what makes them special.
