"Forget yesterday - it has already forgotten you. Don't sweat tomorrow - you haven't even met. Instead, open your eyes and your heart to a truly precious gift - today." This quote conveys the message that the author John Green, had for teens while reading The Fault In Our Stars. Throughout the novel, John Green sent a message to teens that you should appreciate the time you have together with someone because you don't know how long you have together. "There are days, many of them, when I resent the size of my unbounded set. I want more numbers than I'm likely to get, and God, I want more numbers for Augustus Waters than he got. But, Gus, my love, I cannot tell you how thankful I am for our little infinity. I wouldn't trade it for the world. You gave me a forever within the numbered days, and I'm grateful." (Page 206). This quote emphasizes the message on how Hazel cherished the time she had with Augustus. She didn't know how long she had with him or what would happen, but she took a chance and chose to live her little infinity with him. Brooke Osiel, stated in a group discussion that she felt that Hazel changed her outlook on life as a whole. "Hazel was brave and although she feared that she was a grenade, she lived her life as she was not terminally ill and embraced everyday that she had with Augustus, like it was her last." Throughout the book, another important message was to live everyday, as it is your last. "I tried to tell myself that it could be worse, that the world was not a wish-granting factory, that I was living with cancer not dying of it, that I mustn't let it kill me before it kills me" (Page 121). This quote shows how Hazel did not let her cancer get in the way of her living. Whether it was going out with Augustus or taking an adventure to Amsterdam, Hazel and Augustus embraced each day as it was there last. They took on new adventures together and lived as they had all the time in the world.
