i agree because life is hard, and there are so many journeys we have to go through, and those journeys will only be easier if we understand that not everything is perfect and going to go your way.
Macbeth's "tomorrow and tomorrow and tomorrow" speech in Act 5, scene 5 acts as Macbeth's farewell. In it he thinks about the meaning of life and decides that death is something that comes to everyone, people are all just walking the earth with no importance. "Signifying nothing" at the end refers to man's life, it means nothing, according to Macbeth. He relates a person's life to an actor who plays a part on a stage for a couple hours and then disappears, doesn't exist anymore.
This speech shows that he has essentially given up (in his mind) and thinks that life is meaningless.
The Greeks believed that no man could be considered happy before his death, since the happiest life could be destroyed in an instant. Sophocles states this outright both in <em>Oedipus Rex</em> and <em>Antigone</em>: both Oedipus and Creon begin as wealthy, proud men who rule over the city, but they end up ruined and defeated. The element of tragedy that is mos apparent is the belief in the frailty of human life, the vulnerability of even the greatest individuales to the whims of both fate and the gods, what George Steiner termed "absolute tragedy".
