The French writer Maupassant once said confidently in front of Flaubert when he was a child: "I spend two hours in the morning reading and writing, and the other two hours playing the piano. In the afternoon I spend an hour learning to repair cars from my neighbors, and spend three hours practicing playing football. In the evening, I will go to a barbecue restaurant to learn how to make roast goose, and on Sunday I will go to the countryside to grow vegetables." After finishing speaking, he looked proud. Flaubert smiled and said: "I spend 4 hours reading and writing every morning, 4 hours reading and writing in the afternoon, and 4 hours reading and writing in the evening." Flaubert then asked: "What are your specialties? For example, what kind of things do you do particularly well?" At this time, Maupassant could not answer. So he asked Flaubert: "So, what is your specialty?" Flaubert said, "Writing." It turns out that your specialty is to concentrate on doing one thing well.
