In Shakespeare's "Hamlet," the advice "Neither a borrower nor a lender be" emphasizes the dangers of engaging in lending and borrowing. It suggests that such financial dealings can lead to the loss of both money and friendships. This warning reflects the idea that when one borrows, it may weaken their ability to manage their resources effectively, which is described metaphorically as dulling the "edge of husbandry," or the skill in managing one’s affairs.

The quote highlights the potential pitfalls of financial dependencies, which can strain relationships and disrupt personal stability. It serves as a caution against allowing debts to compromise one's integrity and interactions with others, reinforcing the importance of self-reliance and prudence in both financial and personal matters.
