A Road to Common Lisp (2018)
I was exposed to Common Lisp in college in a "Programming Language Concepts" class, almost 20 years ago, and it didn't "click".  I got no help or assistance or explanation, and this was pre-youtube and Google so it was hard to find an answer to "why is this happening?"But I gave Clojure a try despite the bad taste in my mouth Common Lisp left, and it was def worth it.To try it out real quick: https://tryclojure.org/
