Moment

The man doesn't choose the moment, the moment chooses the man.

A simple but often overlooked axiom -- things that are finite are considered special.

"Special Sale -- hurry ends soon!" "I'll have the special" -- it wouldn't be special if it was offered daily. "Life is precious".

In this case, the reverse is also true -- special things are also finite.

Life is replete with special moments, turning points, forks in the road... but they are just that: singular moments in time. Don't blink or you might miss them.
