For all you struggling would-be bloggers out there (I know a few are reading this): The Infinite Mind discusses writers block
They talk about the science behind writers block, and why some people may be blocked when it comes to writing their thesis, but they can blog eight hours each day. (obviously that is not my problem... if I was blogging eight hours each day you would surely see a little more than this).
It was interesting in that a lot of the ways they talk about writers block apply to me in terms of work, be it thesis work, programming work, planning a vacation work... anything that is on my "to-do" list causes a block for me. That's why I take so many photos. "Take more pictures" is not on my list... it's what I do to avoid doing the things on my list.
As far as the actually writers-block aspect (as opposed to workers-block) I should have listened to this a few weeks ago when trying to write the essay (which I find out now may not be actually published anyway... despite the project leader clearly telling me that she had a commitment from some sympathetic publisher who specializes in publishing things that probably wont sell)
