Overall, this essay does a great job of exploring the idea of bravery and how it can help people achieve the impossible. The essay is well-written and provides good examples to support its argument. One thing I would suggest is providing more information on the three pieces of supporting evidence (the novel, the news article, and the poem). For example, what specific things does each one of these sources say about bravery and the impossible? This would help readers to better understand the argument being made.
