In Shakespeare's play "Macbeth," the quote "Let every man be master of his time" encapsulates the theme of personal agency and control over one's destiny. This line suggests the importance of seizing opportunities and taking charge of one's life decisions, reflecting a desire for autonomy and the right to manage one's own fate.

This sentiment resonates throughout the tragedy as characters grapple with ambition, moral choices, and the consequences of their actions. Ultimately, the struggle for power and time management leads to dramatic outcomes, highlighting the tension between fate and personal responsibility in human life.
