How did the characters in House On Mango Street maintained strength and happiness in the face of struggle and injustice?

This is only a short answer space. I can comment on the protagonist. Esperanza does not want to belong to her impoverished neighborhood and dreams of one day owning a home of her own, different from her families ramshackle dwelling on Mango Street. Throughout the course of the novel, Esperanza invents the person she will become: she aspires to be a writer and to overcome the limitations gender, race and class has placed upon her. She is resilient to the many forces that want to keep her down.
