I have tried several times to learn Haskell. The only resource that actually worked for me was Philipp Hagenlocher's "Haskell for Imperative Programmers".
It is incredible. He does an amazing job of starting from the basics and then diving deep. After going through the series I had a solid enough grasp on the language to use it for practical things.
