Clean Slate

My rants on having a largely bad job.

Why do I write such awful things on my slate?
Anger and bitterness in large, bright letters
Jealousy and insecurity to fill in the lines
I don't mean to write such things
But the damage is done
And I'm left to pick up the pieces
I wish that I could go back
Wipe the slate clean
But sooner or later
The writing will begin again
What will you write on your slate?
