It is not easy to bring up nine children and make them mature. Kennedy's mother Ross devoted all her efforts to this. She once said in her autobiography: "I regard raising children not only as a kind of love and responsibility, but also as a profession, which is as interesting and charming as all glorious occupations in the world." She also said that she would rather be the mother of a great son or daughter than the author or painter of a masterpiece. "What can make a mother yearn for more than the hope of cultivating a great son or daughter?" Therefore, Kennedy became a great son, which is inseparable from his mother's noble maternal love.
