Nihil . . . semper floret: aetas succedit aetati.
M. Tullius Cicero, Philippics 11.15.39

(pron = NEE-hill SEHM-per FLOH-ret AI-tahs sook-KAY-det ae-TAH-tee).

Nothing lasts forever: one age succeeds another.

Comment: Cicero makes his observation about big time periods and perhaps larger
than life issues. His beloved Roman Republic was about to pass away, and the
Roman Empire would, eventually, succeed. The Roman Republic has taken birth at
the end of a troubled monarchy, and itself had gone through a number of
experimental or evolving stages to reach the form that it had when Cicero
defended it.

But, Cicero's observtion is true of this moment as well. No moment, no
experience flourishes forever. Each moment is succeeded by another. In
observing that, it is easier to allow each moment its glory, and to enjoy each
moment, but, also to let go of each moment.

I recently read a quotation from a Zen master giving advice along these lines:
clinging to the moment means you have a problem and a very narrow way.. Let go
of the moment; let go of ideas and experiences that are passing. Concern
yourself only with this: what is good for other people.
