I believe most people who learned programming with C, Java, VB or Python have a hard time to learn Haskell, Forth and Lisp because of their approach. If you really want to "get" Haskell, Forth and Lisp you have to "think" their way. There is a good reason why one of the most important Forth books was titled "Thinking Forth". Lisp is also very different from C and Java, and you have to change your thinking radically to understand and to apply the power of Lisp. Now I am determined to learn Haskell, and I believe that I have to change my thinking much more into a mathematical approach.
