What were two quotes that were vital in Ishmael's survival?

From the text:

When I was very little, my father used to say, "If you are alive, there is hope for a better day and something good to happen. If there is nothing good left in the destiny of a person, he or she will die." (Page 54)

When I was a child, my grandmother told me that the sky speaks to those who look and listen to it. She said, "In the sky there are always answers and explanations for everything: every pain, every suffering, joy, and confusion." That night I wanted the sky to talk to me. (Page 166)
