As a friend once pointed out, the crotchety dowagers do tend to get all the best lines. That may be why I have so many of them in my books.
I went to grad school with the grand plan of getting my Ph.D. and writing weighty, Tudor-Stuart-set historical fiction - from which I emerged with a law degree and a series of light-hearted historical romances about flower-named spies during the Napoleonic wars.
I'm not sure that teaching a Core course is necessarily the best introduction to teaching.
'Purple Plumeria' I dithered over for months and then wrote the whole thing between the beginning of July and end of August. The dithering and procrastination time was three times the writing times.
The minimum I need is six months to allow for dithering, procrastination and the research. The research times varies from book to book; some are faster because they're based off resources I have at my disposal.
