"I failed in the exam," I said in despair.
"Oh." Mom nodded and continued, "Son, just because you didn't do well in this exam doesn't mean you will take it next time. You just have to work hard in the future. Failure is a common occurrence in military strategists. You should treat your achievements with a normal heart. Sunshine always comes after a storm. As long as you work hard, you will succeed. We are proud of this.
