The noise within versus the noise without

They compete: which has the greater clout?

My mind sways from one to the other

Is there a way to find a tether?

As my mind flits, my focus shatters

I cannot let it loose: work matters

To drown one noise, another won’t do

Still my mind I must, without further ado

A goal I must have, to shut out the noise

I need to think about it and give it voice
