What quotes show Esperanza trying to survive?

Esperanza felt like she had failed Mama in some way and wanted to make it up to her. Mama had been strong for her. Now it was her turn to be strong for Mama. She must show her that she didn't need to worry anymore. (Chapter 10)

Josefina had told Esperanza that if she was a good worker, the bosses would not concern themselves with her age, so she knew she had to work hard. (Chapter 10)
