At this juncture, while you are deliberating upon what your work is all about; a very good (if not indeed downright crucial) question is why you are doing what you are doing. Differently put -
what is the burning query that you are seeking an answer to? Such a quest does not only cover one project, it is not even about any of your output in general - instead it is about "you," the person who makes the stuff.

So, ask yourself. And then write down the answer. Again - not in long winded, over-intellectualized terms - not as an abstraction; but as a very real, tangible state of mind or as a quest that can be phrased in simple, clear language. I have a sense that pinpointing this will help you enormously in situating your practice - without which I do not think that you can really write about what you do with sufficient authority.

The question (and the answer) may or may not appear in your paper. In fact, most probably it won't do so. So, this exercise is for yourself, to help you come to grips with why you do what you do - out of which will then come the content of your text, since this will be about one of the things that you have actually created as a result of this global mindset or quest, which is simmering in the background, throughout your psyche.
