I love photographs of the Planet Earth from Space. They tend to give me an immediate perspective no matter what is going on in my life. This photo is actually a composite of many photos over many days that NASA scientists put together. I also love how that reminds me that the World is like a patchwork of all different people and places throughout time.
On a much less philosophical note, I believe the Discovery Channel "The World is Just Awesome" song says it exactly right. This song never gets old for me.
What can I say? Boom de ah da.
