It just amazes me that this one song can mean soo many different things to so many different people. I have heard this song interpreted so many different ways. These lyrics can bring inspiration, reminders, hope, and so many different things. To me, it is just sort of a reminder to keep going, don't look to the end. I have heard people say they think he may be speaking of cancer, some of the tragities of 9-11, that hes speaking of life being surreal. All different things.
