LISP is way over my head. The entire recursion based theme of LISP does not click with me, and it is entirely my fault. I tried and I barely passed my LISP class. It was though. I remember having problems writing even the simplest code - like Fibonnaci in LISP... If you know how to code in LISP, you surely must be an android.

You don't have to write recursion-heavy code in Lisp. You can if you want to, and it hurts less than doing the same in many other languages, but iteration in Lisp works just fine too. (The Common Lisp LOOP macro basically gives you a little embedded language just for expressing iteration. So does ITERATE, which some people prefer but isn't in the standard.)
