The title is a bit over dramatic but, per the title, if you could contribute with one piece of knowledge to a book that every single individual should learn from in order to kickstart a civilization, what would be yours?
My personal choice would be the process of soap making, from scratch.
I can periodically dust the book. When I’m not dusting, I can stand somewhere conspicuous, and say “This way to the book” if asked.
Can I give you holiday cover? I’d like this job, like some sort of holy librarian.
Yes of course. With all vested powers I dub thee Venicon, Librarian Most High, Director to the Book. We only have the one, but it is quite good.
Welp, looks like my LinkedIn is getting an update.
The All Mighty Guardian of the Book, Keeper of Knowledge.
You will also be required to know it by memory cover to cover and read it on request for anyone.
Then my knowledge of my own limits must. Be my contribution to the book.
