There's no limit to how much we can see and learn in one lifetime. Experience leads to perspective, perspective leads to wisdom, and wisdom leads to contentment. The minute we stop using outward pleasures to attain inner peace we can transcend the mundane and hopefully, if we try our best, change this world for the better in our brief time here. I chose this picture of Ta Prohm Cambodia because it represents the amazing things out there in the world waiting to be found and learned from.
