The quote from Hilary Mantel's "Bring Up the Bodies" reflects the concept of seizing opportunities as they arise. It suggests that when good fortune presents itself, it is essential to be vigilant and prepared, standing ready to welcome it. The imagery of someone planted at the door emphasizes the proactive stance one should take towards opportunities, rather than waiting passively for them to come. This readiness to embrace fortune can lead to significant outcomes in one's life.

Furthermore, the passage captures the relationship between effort and success. The character’s position by the door signifies a commitment to act decisively when chance knocks, reinforcing the idea that fortunes do not just happen—they must be welcomed and acted upon. Mantel's choice of words personifies fortune as a timid entity, which reinforces the idea that good opportunities may initially appear uncertain or fleeting, highlighting the importance of being attentive and responsive when they present themselves.
