Tom,

Indeed, clearly I have pyrotechnics on the brain or something. Corrected!

I think you mean ammonium persulfate and not perchlorate.. still got perchlorate on the mind I see!

In my opinion desire deprivation is the root of most depression, affective or creative in nature.

A powerful observation Alan. Despite my near-idyllic geeky life style I have periods where motivation evaporates. I have learned just to plod along and ride them out. Some new opportunity that puts me under a little time pressure and/or a chance to travel seems to kick me back to the opposite - working too hard but perhaps more content overall.

My wife has observed that exercise seems to help - everything looks a little brighter when illuminated by endorphins.
