A riddle for you:

What can't money buy?
Once it is gone you can't reclaim it.
You have to use it now.
We all receive the same amount each day.

The answer: Time
~~~~~~~~~~~~~~~~~

Yesterday … Like mintage spent, is past recall;
Its echo dimmed beyond time's wall.
Tomorrow … It never promised earthly man,
Nor does it often fit a plan.
Today … Is gold that covers hills and dell
And rich are they who use it well.
