The author speaks of "building and building again, even after crumbling," using a phrase that permeates her life. Everyone lives building a tower within their hearts, where effort, goals, relationships, responsibilities, and the totality of life experiences form a single tower of the mind. However, the moment that tower collapses, humans face a harsh reality. Kim Dong-hee likens the act of setting a new direction and moving forward, rather than giving up in the face of that collapse, to the act of building a stone tower.
