Another thing you can do is look at the frontispiece of Miles Reid' Reid's commutative algebra book (click the frontispiece link in the contents; Google books won't link directly to the right page). It's subtitled "Let A be a ring and M an A module". I think the picture shows pretty much everything, how the module looks over the generic point, it's support and so on. You can find it easily be googling "miles reid commutative algebra" and opening the link to the gooogle-books page. If you look at the picture it's really easy to remember Nakayama's lemma, just as ilya said.
