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/
If you want to learn CL, try this https://github.com/ashok-khanna/lisp-notes
I posted it earlier in HN as it helped me a lot but didn’t get any responses. I should sponsor the guide’s author, he or she has written lots of useful notes on CL on Medium
