“Better to light a candle than to curse the darkness.”

"Don't it always seem to go
That you don't know what you've got
Till it's gone"

Duality, one half can't be appreciated without the other. I detest night shift, but finishing one, gives me a temporary vigour. Sadly the same applies to almost everything, the onset of winter makes Summer seem sweeter. The biggest cliche of all, but so so true, you don't know what you have until it's gone.
As I said to Billie the other day (or something like it at least), "you don't know you are in a golden age, until it has passed."
The principle applies to people too,
here endeth the lesson.

“Do not anxiously hope for that which is not yet come; do not vainly regret what is already past” - Chinese proverb.
