Describe delay in "Hamlet" that is displayed in the character of Hamlet.

Ham:  Denmark's a prison.

Ros:  Then is the world one.

Ham:  A goodly one, in which there are many confines, wards, and dungeons.....

Ros:  We think not so, my lord.

Ham:  Why, then, 'tis none to you; for there is nothing either good or bad, but thinking makes it so.  To me it is a prison (II,ii,236-242)

This man of thought, Hamlet, is also a man of great melancholia.  And, it is this melancholy and imprisonment, as it were, in depression--recall his debate of even existence in "to be or not to be"--that also contributes to his lack of decisive action.
