The quote from Sylvia Plath's poem reflects a sense of impending change and possibility. By stating "We shall by morning inherit the earth," the speaker expresses a hopeful anticipation for the dawn of a new era or transformation. It suggests that a new beginning is just on the horizon, implying a shift in power or perspective that is about to take place. The notion of inheriting the earth hints at empowerment and the potential to reshape one's surroundings.

The phrase "Our foot's in the door" reinforces the idea of opportunity and access. It implies that progress has been made, and there is now a chance to step forward into a new world or situation. This imagery of being poised to enter strongly conveys the spirit of determination and readiness to embrace what lies ahead. Together, these lines encapsulate themes of hope, renewal, and the promise of change inherent in human experience.
