In the Murk

Concentration’s difficult
When one is feeling spent.
You start to wonder where the hell
Your mojo up and went.

The brain can only function
When it’s soothed by lots of rest.
Each of us knows just how many
Hours might be best.

Guess I must be running short
‘Cause thoughts are all a’fuzz.
Sentences begin and then
I don’t know where I was.

Time to pack it in for now;
I’m drowning in the murk.
Tomorrow I’ll be fresh and clear
And ready for some work.
