Don't know if it counts, but I'm currently writing a book on my religion's thealogy (no, not a typo).
It's one of the reasons I turned to Learning Strategies Corporation - there's no way I can assimilate the massive amounts of knowledge I need to write this book without PhotoReading, unless I'm willing to take a VERY long time.
My current phase is studying ontologies in order to have a clear metaphysical stance. It's difficult, as I naturally find myself becoming more and more of a positivist as I age. I guess a natural part of growing up is having one's certainties turn out wrong so many times that one becomes less and less certain. This, perhaps, is wisdom - the willingness to have one's beliefs challenged and adjusted. LSC has helped a lot with letting me know in course after course, tape after tape, that it's not only OK not to know everything, but BETTER to not know everything, because the less we assume as certainty the more room we have to learn and to improve our knowledge and ourselves.
Whoah, how's THAT for a tangent!
