always changing and forever the same

Everyonce in a while you have those moments where you realize how truly small you are in the insanely large world you live in. How insignificant your life is. And yet you smile, because even though you know that the world is much bigger than you can ever possibly imagine, there it is, a nearly never changing constant. Sure time passes, the sun sets, and the world turns and it seems near crazy that we would call it anything but constant. People change I guess, but its not so much change as it is growth, which in it self is somewhat of a constant. Our opinions change, life experience gives us invaluable knowledge and yes we change and yet I still feel like in someways everything is the same.
