The world citizen concept is intriguing to me because it causes us (I certainly hope it does anyway) to live outside ourselves, considering others, and having compassion. The tragedy in Japan is the most recent event that helps us understand this situation.
The thing that intrigues me the most about being a world citizen is that I should be moved to action when another has a need, no matter if it is on the other side of the world. We can help. It's almost like we have one voice with many languages spoken.
A song that is heavy on my playlists is One Voice by The Wailin' Jennys. Enjoy this video and think about being a world citizen.
