Everyone knows that diligence is the key to success. As a proverb goes: “Diligence is the mother of success.” Diligence means working hard and persistently.
All famous people of great achievements are examples of diligence. They all owe their success to hard work. without constant efforts, no one can expect to succeed in doing anything great. Thomas edison kept on working hard for a long time before he was able to invent he electric light. Madame Curie worked hard in the poor conditions for many years before she finally discovered radium. Some people may attribute success to good luck, but good luck favors those who are well prepared and diligent people who can make use of it. So idleness can only lead to poverty, if you do not devote yourself to your study and work, you can hardly make a living, let alone make some accomplishments.
As high school students, we must be aware that the only way to success is hard work. We must concentrate our attention on our studies, and make full use of our precious time, in order to meet the fierce challenges in the future competitions. It is certain that our future success will only rest on our constant efforts. As a proverb goes: “Only by working hard can we reap a bumper harvest.”

The proverb “no pains, no gains” means that you have to make great efforts if you want to achieve success, for nothing but poverty can be obtained without effort.
In history, there have been many famous people of great achievements. You may claim that they are geniuses, but behind their successes, they have made great efforts in carrying out their tasks. Einstein said “genius is one percent of inspiration and ninety-nine percent of perspiration.” He had been working hard for many years before he finally worked out his theory of relativity. Thomas Edison experienced countless failures before he finally invented the electric bulb. Wang Junxia was able to win the world championship of long distance race only because she had many years of hard training. therefore, diligence is the key to success. Doubtless hard work promises fruitful result. Everyone is awarded the right to work hard in order to reach his goal. Apparently, diligence is necessary to success. Happiness is nearly always a reward for hard work.
On the other hand, idleness is believed to be the root of all evil. anyone who habitually likes idling but desires everything is daydreaming. We should be aware that if we dream away our precious time, when we wake up, it may be too late for us to achieve anything. So, as college students, we should never stop working hard so that we will remain successful in the future competitions.
