Have You Heard?

Hearing voices, often taken to be a sign of something wrong in the noggin, occurs in many people who seem to be fine.

The voices in my head?
Don't tell them to be quiet.
They'll stop when I am dead.
Till then, they all run riot.

I don't always pay attention
To what they have to say.
I brush off their dissension
When I've settled on a way.

But frequently, I listen,
Because of what I've heard -
That precious bits of wisdom
Might show up in these words -

And I don't wanna miss 'em
When that finally occurs!
