My biggest poetic influences are probably 20th-century British and Irish poets. So I suppose I'm always listening for the music I associate with that poetry, the telling images, the brevity. I want to hear it in my own work as well as in the poetry I read. However, I think I'm generally more forgiving of other poets than myself.

Embrace the melancholic voice completely in the drafting stages, to explore it for all it's worth. Then, in revision, privilege craft over pure feeling. Write the work that someone besides you will want to read.

I think my cheerfulness keeps my writing from sinking into the depths of melancholy, while the darker side keeps in check any literary silliness I might be inclined toward.

Compare the scale and magnifcence of Versailles with St James's - the brick-built hovel in which the 18th-century kings of England lived. What was then the most powerful monarchy in the world housed its sovereigns in a converted leper hospital, yet, at the same time, parliament provided the magnificent palaces of Chelsea and Greenwich as hospitals for retired soldiers and sailors.

Once a piece of writing gets to a moment where it's not going to get much better than it already is, marinate it. If you still like the piece, send it out and see what others think. If not, it's time to put it away and forget about it for a while.

I think I give far more space and play to avant-garde writing than any other contemporary textbook author. I want students to be able to decide for themselves which aesthetics are closest to their own. Still, while I try not to be a nostalgist myself, I suppose I am drawn to those poignant moments in our lives, rendered clearly and artfully.

Out of the chaos of post-Roman Dark Age Britain, the English had created the world's first nation-state: One king, one country, one church, one currency, one language and a single unified representative national administration. Never again in England would sovereignty descend to the merely regional level. Never again would the idea of England and the unity of England ever be challenged.
