I've come to pretty much the same conclusion as the OP. I used to love learning and trying new languages and I agree that learning things like C and Lisp and Haskell definitely made me a better python programmer. However over the past few years I've decided that python, while far from perfect, is the only language I've found that is good enough for everything I want to do. And more importantly I've realised that learning new languages is not the best use of my limited time. I'm much better off studying a new domain or practical application which I can apply python to than I am learning a new language do to the same thing I'm already doing in python.
