I heard someone on the radio the other day talking about how many of the things we thought were true have come undone. Take the value of something. A year ago, many people thought their homes had value. They may have based all their decisions on this assumed value. But then something happens, something unpredictable, and suddenly their home has no value. He talked about how a mining town in Arizona once boasted beautiful homes worth around $200,000 a piece. But once the mine closed, these homes were suddenly worthless. His overall point was that the only thing in life that is worth anything is love and spirituality.

But really, love can change overnight too. Haven't we all known couples who seemed so deeply in love on their wedding day and within a year or two were vowing never to spend another day together? Were they really in love or can things change so quickly?

And spirituality, well, people change religions. They lose faith. They are born again. Certainly faith evolves.

The only constant, then, is change. It's hard to plan a life around that. But that's what we're supposed to do.
