This page titled, “What I wish I knew when learning Haskell” has this interesting section on monads. I agree with his statement that there’s no sense in studying monads; you just need to write a lot of FP code, and then you’ll see when you need a monad. That is, studying monads is like studying OOP design patterns when you don’t need them; they’re interesting to learn, but until you need them and use them you won’t really understand them.
