Writing from Your Own Emptiness

I have just found yet another reason why I'm drawn to the boys from Dublin. 
I remember as a child, growing up in Ireland. We were taught the poetry of William Butler Yeats. I must have been ten years old. The teacher said, "and then Yeats went through his dry period. He had a writing block and he couldn't write about anything." I remember putting up my hand, and saying "Well, why didn't he write about that?" And the teacher just looked at me and said, "Oh, be quiet." But that is exactly the answer to the writing block. You write about your own emptiness, and we've done that for years now.
