What are some lessons Meg learns about herself in A Wrinkle in Time by Madeleine L'Engle?

Meg Murry
views herself as inadequate. She may be bright in some school subjects but she is horrible in
others. She has very few social skills and few friends. She sees herself as an extremely flawed
individual. When she meets the three Mrs. Ws, she learns a different view of herself. In
preparation for her return to the planet Camazotz, Meg is given a gift from Mrs. Whatsit; she is
given her faults. Meg objects that she is always trying to get rid of her faults; she does not
see how these can help her to attack evil. Yet she learns that her faults are often the flip
side of strengths. Her impatience leads her to be persistent in attacking IT. Her capacity to
love unhesitatingly helps her to rescue Charles Wallace from his possession by IT. She learns
that she does not need to be perfect, but can find strength in being herself with all her
flaws.
