John Green spent his life with people who were on the verge of death. He worked as a student chaplain at a children's hospital. He saw lots of positivity, from families praying together to the perseverance of a patient; but he saw negativity as well. The sorrow of a person when someone passed away, and the look in the patient's eyes when they knew there was no hope. The deaths of so many young people affected him the most. They had so much potential! "To see young people die and their families torn apart, it was just devastating," Green said. Though he left his chaplain days behind them, he wanted to write a novel about those days and the pain these children had to go through. He wanted people that could easily relate and were around that age to understand. He wanted to make something positive about something negative. So he started his book and the first draft didn't go so well. He kept trying but they weren't good enough. Then he met Esther Earl and she changed his life and his attitude. It also made i=his book a best-seller and he became a world-renown author. One person changed his life and career! And that is how John Green wrote his fourth, and best book.
