Tomorrow, and tomorrow, and tomorrow,
Here, Macbeth is full of despair, and he is seeing life as a story and death as a natural occurrence that is to be welcomed.
I personally think that life is nothing if we don’t believe in something. If you don’t believe in yourself, would you be able to succeed in life? If you don’t believe in your partner, would you be able to live a happy life? If you don’t believe in God, would you be able to feel the peace?
If we don’t believe in something, life is absolutely nothing. It’s meaningless. We’ll be nothing but actors in a play, where our world become the stage.
