"How much have you written in the first week?"
Not one word.

"How do you feel about it, positive or negative?"
I'm okay with not writing. Writers spend the majority of their time not writing. It's natural to want to go outside, to eat, to sleep, to talk to our loved ones or our tolerated ones. Beyond that, many of us have jobs or other obligations which demand our attentions even during times when we would actually prefer to write, or so we tell ourselves. But just because I haven't touched pen to paper doesn't mean I'm not mulling it over, not letting words wash up on the beaches of my mind. The process is already begun. 

"Do you have a set goal in mind or could all your plans change tomorrow?"
My plans do change, with every tomorrow.  

"What's the most difficult part of writing so far?"
Apparently the writing part.
