Great post and the only thing i would add is the value of physical books. Information is power, people are too used to just googling it or watching a youtube video to figure it out. Get the manuals for your equipment, have books on repair and building, recipes, canning times, etc. A book can be read by candlelight or daylight, if the grid is fucked you have no online resources to go to.

Own books, read to your children, and teach them to read. Do NOT trust any teacher to do this for you. Ensure your child can fucking read, and work on speed reading as well if you are able.

And I know im wasting my digital breath here but have actual books like farming, gardening and repair and not useless holy books. A book on edible plants found in your region is infinitely more valuable.
