McGovern's legacy also includes his commitment to combating hunger both in the United States and around the globe. He said, "After I'm gone, I want people to say about me: He did the best he could to end hunger in this country and the world." In the view of Knock, McGovern in all his activities arguably accomplished more for people in need than most presidents or secretaries of state in U.S. history. Responding to the Serenity Prayer's desire to "grant me the serenity to accept the things I cannot change", McGovern said simply that he rejected that notion: "I keep trying to change them."
