I've tried to go to lisp, and failed. Later I tried to learn haskell (to contribute to pugs), and failed again. Either it was the different model of thinking that I don't really grok, or it's my impatience. When I learn a language, I code a few small things, but if I fail to see how to do more complex stuff, I quickly fall back to perl.

I'm now trying to learn Perl 6, which is, among other things, lisp with non-lispy syntax ;-). I hope that the different syntax cheats my brain enough so that I'll succeed this time.
