"All the world's a stage, and all the men and women merely players: they have their exits and their entrances; and one man in his time plays many parts, his acts being seven ages"

This quote by William Shakespeare is a metaphor for life. It recommends that life resembles a stage play, with everyone contributing. Everybody has their own entryways and exits, and each person goes through different stages in life. The seven ages pointed out in the quote refer to the 7 phases of life, which are infancy, childhood, teenage years, young adulthood, midlife, old age, and death. This quote is a tip that life is short and that we need to take advantage of it. It also motivates us to be conscious of our actions and to be aware of the impact we have on others. Eventually, it is a suggestion that life is a journey and that we must strive to maximize it.
