The quote from Margaret Atwood's "Alias Grace" suggests that revealing one's needs or vulnerabilities can lead to exploitation. When others become aware of what you desire or require, they may use that information as leverage, which poses a risk to personal autonomy and security. This highlights the importance of self-sufficiency and the potential dangers of dependence on others.

By advocating for a mindset that minimizes desires, the quote encourages a form of emotional resilience. It implies that by lessening our wants, we can protect ourselves from manipulation and maintain control over our lives. Ultimately, it reflects a deeper theme of personal strength and the complexities of human relationships in the face of power dynamics.
