I wonder why the inspiration to write
Comes at the most inopportune time
When it’s time to study or read important articles
I instead want to write
And when there’s nothing else I’d have to do
I can’t come up with even just a single line
Why, oh why, my heart and my mind
Don’t seem to meet and rhyme?
