Haskell clicked for me after I finished several basic katas on Codewars in parallel with Clojure. It's essentially Lisp without brackets and with other weird syntax choices.
Nevertheless, I was advised on the /emg/ that Clojure is the most marketable Lisp and more marketable than Haskell. It's ecosystem is quite thriving from the first glance. And definitely not:
Lisp? Nobody cares about it.
