I used to have a teacher who said this as well. The best way to understand would be to show examples of how to specify such terms as “stuff” and “things”. For instance: “The birds have lots of stuff.” That was not clear because the reader does not know what the “stuff” is. Instead, the text could be changed to: “The birds have lots of feathers.” Now the reader knows what the stuff is because it has been replaced with a more specific word. If you go over multiple examples in your head, it will become easier to comprehend and you will get used to doing it.
Shakespeare's intention was not to make Shylock a tragic figure; instead, Shylock was meant to function as a man who could be vividly realized as the epitome of selfishness; he must be defeated in this romantic comedy. In a sense, it is Shakespeare's own brilliance which led him to create Shylock as almost too human. Shylock is powerfully drawn, perhaps too powerfully for this comedy, but his superb dignity is admirable, despite the fact that we must finally condemn him.
