All the above suggestions are good. In addition, I've learned a lot by
doing the problems at 4clojure.com.

The code in question is a solution to http://www.4clojure.com/problem/58

Hi, Randy,
I'm several years into learning Clojure. Here's what has worked for me:
* Use either Light Table or (if you're determined) Emacs as your IDE.
* I learned a lot from taking this free online course:

George, I don't know why it works (my init.el file doesn't seem to
mess with anything), but adding that code to the end of init.el makes
things work. You're doing great things for the Clojure community--many
