参考答案： Key Factors to Success
That everyone wishes to be successful in life is beyond doubt. To succeed, three fundamental principles should be borne in mind.
The first key factor to Success is diligence. Diligence can help us remove ignorance, overcome difficulties, and enlighten our minds. If we while away our time now, our future life will be a failure.
Devotion, which means the concentration of our mind and effort in doing things, is another key factor to success. Whatever job we are doing, we must love it and do it whole-heartedly.
Perseverance, or a strong will, is also necessary in order to make success a certainty. If we study and work day after day, there is nothing that cannot be achieved.
To conclude, all great men achieve success through diligence, devotion, and perseverance, just as the famous English saying goes: no pains, no gains.
