Once I get done rolling the rock up the hill, it rolls right back down

I have discovered that in order to be a tech writer, you basically have to be an existentialist. You're stuck in an endless cycle of re-writes and updates, and the only way to find any sense of accomplishment in the job is to take pleasure in this cycle. I've found that I can do this, so I join the company of Sisyphus in Hell, doomed to roll a rock up a hill, knowing full well that the moment the rock reaches the top, it will just roll right back down. In the same way, the moment I finish a document, there will be a new build of the pertinent software with a completely overhaulled GUI and a whole slough of new functionality, rendering my just-completed document obsolete and useless, such that I must start again from the beginning and repeat. It is times like these that I am glad for my existential leanings, as they manage to keep me sane and productively employed.
