@pfr you can follow lisp related hashtags on fedi (lisp, commonLisp, scheme, guile, emacs), or there are irc or matrix rooms if they're your thing.
there's https://gigamonkeys.com/book/, very well written and fine if you're not a programmer, also https://files.spritely.institute/papers/scheme-primer.html. (for both you'd want to get a lisp or scheme env set up so you can follow along.)
also the little schemer book is cool too, including pedagogically.
(i also learned lisp as a non-programmer, i think it's great)
