Unfortunately, that need to have something to say is also what can paralyze a writer, make writing word one a trial fit for Hercules.
Sometimes we stare at the blank page. Sometimes we just start writing and hope to find the meaning as we go. And often, we fail.
But those few times when it all meshes just right — when the perfect story and its deeper meaning come together like a Reese's Peanut Butter Cup — it's all worth it.
