"No ideas but in things."
~Williams Carlos Williams
As a writer, I've always tried to adhere to this notion. If concepts such as love and death, hate and happiness, estrangement and despair are to mean anything, I have to show it in my work. It's not enough to write great verse around an idea, I have to figure out how to make it resonate for the reader through everyday examples. And that is where craft comes in.
Not all of the poetry I write is good, but I'm not afraid to push an idea up against the wall and interrogate it until it tells me what I need to know.
