In Margaret Atwood's "The Penelopiad," the quote "She who weeps when the sun's in sky, Will never pile the platter high" suggests that those who succumb to despair during prosperous times will miss opportunities for success and growth. It emphasizes the importance of embracing positivity and seizing the moment rather than allowing sadness to eclipse potential. The imagery of the sun indicates hope and abundance, contrasting with the act of weeping which signifies loss and stagnation.

Atwood's work often explores themes of female agency and resilience. This quote serves as a reminder that emotional responses can shape one's life and destinies. By remaining focused and proactive, individuals can ensure that they fully engage with life’s offerings, ultimately allowing them to prosper and thrive in their endeavors. The message is particularly poignant in the context of women's struggles, illustrating how embracing hope and opportunity can lead to greater achievements.
