Nowadays, many people complain to their poor achievements in study. Some are eager to know others’ secrets to succeed, thinking that they should have mastered some specially ability in study. In fact, only by practising a lot can we become skillful at doing nothing. Do you know why a baby learns to speak? He practised his mother tongue day and night and finally becomes fluent in them. So we should well remember that there is no such a shortcut. No one can become an expert without practising a lot. We should bear the hardships in our study, then we can enjoy the fruits of our efforts.
