Reading the books such as "The Joy of Clojure" and "Clojure Applied" helped me to leave the OO behind when getting into Clojure.

I've been going through "Clojure for the Brave and True". It's been great so far, it does a good job of explaining out functional programming.

Though I already had one foot in that realm with playing around with Racket and learning Scheme in college.
