These are all great suggestions but I am still looking for one of them that is beneath what the Tightwad Gazette suggests-- they have some super gross stuff in that Gazette, things that risk health to save a nickel.
I recall several threads on this forum dedicated to using zero soap or hygiene products of any kind which is pretty extreme, but I doubt our MMM thrifty folks were pulling spoiled meat out of a dumpster and hoping that boiling it for hours will kill the disease within.
The Gazette gets weird with folks bragging on washing clothes in their dirty bathwater after the whole family has taken their swim and stuff like that. Can we top that?
I was a huge TWG fan when it first started and still am. Pre-FIRE, I re-read the Big Blue Book annually during my No-Spend February, which I was doing long before it was a "Thing". I still keep a copy for occasional refreshment. I honestly don't remember any of the gross stuff you describe. It may be because the overwhelming impression I derived from TWG is what enabled me to set a course for FIRE long before the term existed. It's quite likely I merely glossed over anything I thought was too gross to try, the same way I did about raising kids, as I have none. There is so much good in TWG that I would have lost had I chosen to be squicked out about a few minor points. I do remember that Amy D used the example of an apple with a single bite out of it to introduce the concept of "Selective Squeamishness". Perhaps I internalized the concept so completely that I do it automatically when I re-read her book.
Amy Dacyczyn was stunningly unafraid to march to her own drum. She invited everyone along for the ride and changed countless lives, including my own. Being non-consumerist is completely against the grain of our modern society, and Amy D was my friend in my sometimes lonely quest for Financial Independence.
One of the things that is most enduring TWG that it's not just a collection of tips, it's a way of thinking, even an overall way of life. It's master recipes that are endlessly adjustable, it's good old common sense and practicality. Last week, at the end of a book sale, I picked up a perfect condition copy of a book compiled from Yankee Magazine, called "Vinegar, Duct Tape, Milk Jugs, and More". It's twenty years old and I'm finding it a slog, because it's pretty dated, boring, and irrelevant, because it's just a collection of tips. The Complete Tightwad Gazette endures, despite being plenty outdated itself, because there's an underlying network of principles that are still astoundingly relevant today.
The old phrase, "Don't throw the baby out with the bathwater" seems to have morphed into the more modern "Don't let the perfect become the enemy of the good." This totally applies to "The Complete Tightwad Gazette".
