What is Macbeths view on life? What 4 images does he use to describe the futility of existence?

In act 5, scene 5, Macbeth receives the news that his wife has died. This prompts Macbeth to express a very negative view of life. He says that it is pointless, for example, and lacking in meaning.
To convey this negative view, Macbeth uses four images: 
He personifies the day as something that creeps very slowly towards the end of time.
He describes a candle as it is being extinguished.
He describes a "poor actor" who performs on stage for a short time and then is never heard of again.
He personifies life as a story that is told by an "idiot." This story has lots of action and noise but has no real meaning to it.
Through these images, Macbeth successfully conveys the idea that life is futile, and this sets the tone for his final battle and the loss of his own life at the hands of Macduff.
