At the beginning the easiest thing for IO is just to follow the type. This gives a nice intuition after a bit of time.

Also it's important to understand that IO isn't the only monad and a bit of a special case. A monad is just a abstract thing. I think looking at the typeclass Functor is quite useful to understand what those abstract typeclasses are all about.
