What are some quotes about standing up for yourself in The Glass Castle?

In chapter 2, Jeanette's father tries to teach her how to swim by throwing her into water and letting her figure it out. This pretty much sums up his approach to parenting in general. He tells her, "If you don't want to sink, you better figure out how to swim." Not only does she figure out how to swim, she figures out how to survive her father's parenting. Jeanette learns to depend on herself for her survival.
In chapter 3, Jeanette says, "I decided to make my own braces." Again, she's learned that if she needs something, she'd better figure out a way to accomplish it herself. How many kids would even attempt such a feat? But Jeanette is determined, sees her own needs, and comes up with a solution.
When Jeanette wants to "correct" a Joshua Tree which has grown sideways, her mother tells her, "You'd be destroying what makes it special. It's the Joshua tree's struggle that gives it its beauty." This sets the tone for Jeanette's struggles and becomes an underlying theme that pushes her to keep persevering and standing up for herself in the midst of her chaotic family life. She doesn't have to conform to what is expected of her by her family. She can create a beautiful life in spite of her struggles.
When the family is living with Erma, Jeanette's grandmother, Jeanette befriends an African-American classmate. Her parents, who have preached nonconformity and the importance of standing up for her convictions her entire life, don't really support Jeanette and are more concerned about having a place to live. Jeanette sees this and says, "Situations like these, I realized, were what turned people into hypocrites." This provides another opportunity when she sees the need to stand up for her convictions in spite of her parents' teachings.
Jeanette explains that their pets were hungry because they could not afford pet food, and she offers them scraps to help ease their hunger. She notes, "Mom liked to encourage self-sufficiency in all living creatures." Here she is undoubtedly including herself as one of the "living creatures" left to fend for herself because of a lack of provisions given to her by her mother (and father). And somehow Jeanette does learn to survive and become self-sufficient in spite of the neglect she suffers as a child.
