I have no degree in biochemistry, neither do I have one in mechanical engineering, as the Army saw fit to terminate both courses before they were finished.
I wrote two plotted books, got some of the fundamentals of storytelling down, then... it's sort of like taking the training wheels off, trying to write a book that's fun in the same way without relying on quite such mechanical or external beats.
