The writing techniques and skills in writing down the bones are interesting and useful. I've particularly liked the work on obsessions, how it's better to just give into these things, at least to a certain extent. If you don't give into your obsessions at least a little bit the rest of your writing will suffer. It's always easier to write about something we're obsessed with as well and having and knowing your obsessions could help you get past a writing block or out of a funk.
