Writers Block

I sit and think carefully,
Thoughts pacing my mind.
Each one quickly considered,
But then hastily declined.

I watch the seconds turn to minutes,
And the minutes turn to hours.
The page is still blank,
As time is devoured.

I tap my pen frustratedly,
And think for quite some time.
But the words don't come together right,
And nothing seems to rhyme.

It's getting late, I'should give up,
I think, looking at the clock.
But then an idea springs to mind,
I'll write about writers block!
