Similarly I also had moments where I knew what to write in certain places, but there were large plotholes in my mind and I couldn't fathom them, or I wasn't excited enough about a story to write it.
However, as soon as I have a dissertation to finish/edit I suddenly have all the ideas for books and characters and all I want to do is spin beautiful fiction and get my ideas out, and writing down some notes turns into writing the first chapter and so essentially what I am saying is I have spent the past half hour not doing what I was supposed to.
Novel, go away. I'm busy with work. Come back and play next weekend and we can be best friends, I swear.
Creativity, thou art a cruel mistress.
