Shakespeare Motivates Shakespeare?

This year, I'm really getting to the bottom of Hamlet, the most bottomless piece of literature in existence, but this means we might never finish-- which is perfectly appropriate . . . I probably need a ghost (played by myself) to visit and "whet my almost blunted purpose" so that I actually finish the thing before the last day of school (that's essentially what happens in Act III scene iv . . . Hamlet's dad returns in the form of a specter that only Hamlet can see and tells him to stop calling him mom a slut and get on with his revenge on King Claudius, the same way Mufasa tells Simba to quit it with Timon, Pumba, and Hakuna Matata and live up to fate and responsibility and go kill Scar . . . but of course, Shakespeare wrote Hamlet's lines-- so when the ghost (probably played by Shakespeare, tells Hamlet to get on with it-- because we're nearly three hours into the play and the plot hasn't really gotten going yet) this is very strange-- it's the director telling the writer (who are both the same person) to stop going so deep with his character because people have to eat dinner.
