When is it time to change?

"Our likes and dislikes as decisive factors have now pretty well disappeared."
Bill Masen, contemplating the post-apolocypse
The Day of the Triffids, by John Whydham

Seems like when we don't have anything, that we desire much. When much is sitting in front of us, it is easy to settle with nothing. And when we have no choice, well, we have no choice.

I wonder why it takes losing so much before we realize what we had. That all illusive search for greener grass on the other side reminds me more of flatlanders on crinkled paper - an imposability.

Somehow, we never seem to learn. As we lie there on our death bed and our life flashes before our eyes, I wounder how many of us will be satisfied that never wasted our time. And the next moment, that could be a minute or a year, or many years later, in ternity, what then? How will we look back at our time on this planet?
