During her 58 years of life, Edna St. Vincent Millay left many works that have made a change in American society. She once said, “this book, when I am dead, will be a little faint perfume of me. People who knew me well will say she really used to think that way.” By leaving this famous sentence, Millay supported Americans to put out their thoughts in words. In addition, she also made young Americans think that they had the ability to change the world by saying, “the young generation forms a country of its own. It has no geographical boundaries. ... These young people are going to do things. They are going to change things." She tried to change the society by supporting these young people to believe in themselves.
