Time to Sharpen up

There are days
when I feel I have no
strength at all.
My outer shell, the facade
that you all look upon,
seems to resemble me,
but lacks substance,
stability... effectiveness.

Do you have days like that?
Days when you feel like
one of those drawer fronts,
with a handle and everything,
but no drawer?

'Plastic knife' days...
when I am a laughable
facsimile of the real thing.
It's like,
"And here's a knife
for you...
but don't try to cut
anything with it..."

I wonder,
if 'iron sharpens iron',
what will happen,
if I am made of plastic?
