I'd have to agree with you. Having read the entirety of LYAH as an introduction to Haskell and functional programming, I felt introduced to a-lot of functional concepts and Haskell syntax. That's unfortunately it. With the absence of practice problems, nothing really stuck, and I'm nowhere near prepared to create a project myself.

Overall, it's not a waste of time, but I'm sure there are more stimulating Haskell books out there that'll better lead you to think in a functional way.
