Everything of value that I've been 'taught' by another has come from family, friends and other wise people, I've meet along life's path, oh and of course Observing Nature..πΎπ±π±πΏππππ (and people watchingπ)
The only 'school stuff' of value I recall, and use to this day, comes from the Arts & Crafts classes i.e. Pottery, Woodwork, some mettle work, basketry, and lots of needle type of work... you know, Useful, logical fun stuff like that..π
