First of all, you should think about the bright side. You have done your math study seriously, so you have made progress in your usual exams. Then you think that the bad side is that you missed the exam because of a small mistake, which led to unsatisfactory results. What is the reason? Because I thought I could do this problem if I studied hard, and the previous exam went well, I was careless, careless, underestimating my enemy, leaning on disasters and avoiding them.
Have you heard the story of a blessing in disguise?
There lived an old man near the frontier fortress. Old people are proficient in numerology and are good at predicting the past and the future. Once, an old man's horse broke free for no reason (probably the mare was in heat) and ran to the place where the Hu people lived. Neighbors came to comfort him, and he knew it well and said calmly, "Isn't this a blessing?" A few months later, the lost horse suddenly went home again, with a good horse of the conference semifinals. The neighbors all came to congratulate his family when they heard about it. The old man was indifferent and said calmly, "Isn't such a thing a disaster?" The old man's livestock has raised many good horses, and his son is martial and likes riding horses. One day, his son rode a fierce horse to practice riding and shooting in the wild. The fierce horse lost control, threw his son heavily on his back and broke his thigh, which became a lifelong disability. When the neighbors heard about it, they came to offer their condolences. The old man said calmly, "Isn't this a blessing?" Another year passed, and the conference semifinals invaded the border and entered the fortress. All the able-bodied men in the four townships and eight neighbors were drafted into the army and took up arms to participate in the war. There are countless casualties. Residents near the frontier fortress, with ten rooms and nine vacant rooms, were all killed in the war. Only the old man's son didn't go to war because of his lame disability. Therefore, the father and son can live and spend the rest of their lives together. Therefore, blessings can be turned into disasters, and disasters can also be turned into blessings. This change is unfathomable and no one can predict it.
So don't give yourself such a big psychological burden. As long as you work hard, you will get something. Success is a harvest, and failure is also a harvest. Only when you have experienced failure can you be truly successful. Only by shooting at the place where you failed and fell can you be in an invincible position!
