As far as being territorial about one's own life, that's a mistake for ANY writer. All writers everywhere, in every genre, are drawing from their life and the lives of those around them for "material." Memoirs just make transparent and even amplify that activity.
Lidia YuknavitchI work from the body - I try to develop a language of the body. I've invented a term I call "corporeal writing" around that idea. I love teaching and collaborating around this idea, because no new breakthrough in literature ever happened because everyone was doing what was already there.
Lidia YuknavitchOne path I've used a lot is to deeply and thoughtfully consider a trope or a tradition, and then set about taking it apart - but only in the service of a character or story that deserves it. Another path I often employ is to put form into "play" - to set it free from its ordinary constraints and let it be free-floating and broken-apart and rearranged.
Lidia YuknavitchPoetry, for example, goes so deeply into the space between corporeal affect and deep emotion (even primal in some cases) that, as Emily Dickinson said, it can blow the top of your head off. Poetic language is sometimes misunderstood as "abstract" when in reality, it's precise - precisely the language of emotions and the body.
Lidia YuknavitchTo be honest, we live in an exciting time where form is concerned. My sincerest hope is that more people will notice this and agree to play and invent - the only way to not succumb to the complacency and market-driven schlock of the present tense is to continually interrogate it from the inside out.
