I was educated by nuns. None of them, of course, did anything resembling the actions of Lydia from The Handmaid's Tale, but they taught me a work ethic, that I had to toe the line, that I had to step up and do my work, and that we would stay until it was done, and that came from a devotion to making you the best person you can be. That's the take I have on Lydia. She knows her actions are firm and sometimes very harsh, but she also looks after them.
Always write your ideas down however silly or trivial they might seem. Keep a notebook with you at all times.
