When we encounter difficulties, most of us will feel pain, just like looking back years later, the whole world is collapsing, there is no hope for tomorrow, the difficulties at that time are just small things, as long as we can stick to these life is beautiful, there is no need to be disappointed in life when we encounter difficulties, just like a popular song, once I fail the exam, how can we be in Seeing the rainbow without a storm, I feel that my world is over, I can't eat well, I just let my parents down, I'm very sorry, my teacher told me, the exam is not a big deal, I should forget it, and then move on, I work hard, try to forget now, when I look back on it, about failing the exam, I don't think it's a big deal.
