第二段：Strong will, perseverance and diligence are the three essentials of success. A man of strong will and perseverance always has an inflexible spirit. He sticks to his cause no matter how tough it might be. Dr. Sun Yat-sen was such a man. Many of his attempts failed, but he held to his purpose with firmness and finally succeeded in overthrowing the Qing Dynasty. Diligence means steadiness in one’s work and study. Su Qin stabbed himself in order to keep attentive to studies. Marx often worked 15 hours a day. Life is short and we have many things to do. Without diligence no one can achieve anything.
