Hard as That, Too

Here is the part both hard and easy:
When you see what’s missing and it’s
all that you (simply) stopped doing while you
went about earning your keep, all the choices
you made in favor of a full wallet, which isn’t
ever so full, is it? Not nearly so full as what
isn’t there, what was (simply) left out
all the songs that you stopped writing all the pages
you stopped filling all the soul that stopped
pouring from your pen. So hard, I know, to see them
not there but not there they are, and the easy,
and the hard: what you pick up, and what you put down.
Simple as that. Hard, hard as that, too.
