"a knack for only that"

"a knack for only that"

my answers all arrived too soon
for me to remember
when the questions came due

so I missed all my chances
by miles or more
with days late adding up to
more dollars short

but there's one thing that I'm good at,
yeah, about one thing I'm good at,
oh, I've got a knack for only that
and that's what's getting me through

my business has a mind of its own
I've been trying to mind it, who knows
where it's gone

or what it's gotten into
whatever it is, won't go well
not for long

'cause there's only one thing that I'm good at,
yeah, about one thing I'm good at,
oh, I've got a knack for only that
and that's what's getting me through
