Orson Scott Card said this quote

Because never in my entire childhood did I feel like a child. I felt like a person all along--the same person that I am today. I never felt that I spoke childishly. I never felt that my emotions and desires were somehow less real than adult emotions and desires. And in writing _Ender's Game_, I forced the audience to experience the lives of these children from that perspective--the perspective in which their feelings and decisions are just as real and important as any adult's. ... _Ender's Game_ asserts the personhood of children, and those who are used to thinking of children in another way ... are going to find _Ender's Game_ a very unpleasant place to live.
