Life is about always looking up. It's a fact that people barely ever turn their eyes to what is above them, for it is always so much easier looking down, observing your feet as they walk along the path. So most people lose moments that they might otherwise have had, moments that could have defined them, changed them beyond belief. They miss all the beauty of the bigger picture.
We all should aspire not only to look up, but also to see; there is a vast difference between the two, and we often forget the latter. For this reason, so much is often overlooked; moments melded into the fabric of Time, and then snatched away, never seen, never remembered.
You may walk with your head hanging down, or your eyes held shut; perhaps living is easier that way. But it is never better.
Walk looking up, walk looking forwards, towards the future, and perhaps you can stop the oncoming traffic and teach them to do the same. Or perhaps you can walk right into someone who cannot help gazing down, and discover what happens when two worlds collide.
