I've been learning Haskell for the last year and a half, though I've been working with functionally inspired languages for 8 years. Haskell is wonderful, easily the most fun I've had learning a language in 20 years.
I'd advise not getting distracted by monads and other glamorous parts of the language. Monads are pretty abstract, and they won't likely make much sense until you've written enough Haskell to feel the pain-points they address.
I've learned a lot by reading blog posts from these people:
Most of all, I advise not getting discouraged. Haskell has a lot of concepts that seem intimidating. Many times I've spent days trying to figure out what the hell a contravariant functor is, only to get really discouraged. At times I've doubted my own abilities and whether learning the language was worth it. I stuck to it, and a year and a half later I'm pretty damn capable with Haskell (and I know what a contravariant functor is!) and I'm having the time of my life learning more about it.
