Achieving Depth

In a profile of Jack Gilbert, "The Ghost Inside," Sarah Manguso asks the poet what he feels is "the most important thing a poet must seek" to which he replied, "Depth and warmth."

Do you agree with Gilbert, and if so, how do you go about trying to seek these and hope they follow through in your writing?

Is there something else you feel is vital for a poet or writer to seek as well?

I'll close this post with one of my favorite poems from Gilbert, Failing and Flying.
