"A person who thinks is a person with unlimited power." Balzac said. In the chaotic study life, my spirit is always highly nervous, and my thinking ability is at its peak. But the arrival of the holiday and the relaxation of my body made me an "empty shell" for some reason. Maybe it's because what I call "thinking" actually refers to thinking in study rather than thinking in life, and I lack observation on the details of life. The trip to Europe brought me a turn for the better. I planted a seed. It was at Versailles in Paris, France. Crowds of white pigeons hover in the sky, people in traditional French costumes in the square dance with accordions, and young people and children indulge boldly and talk loudly about everything. I'm not interested in all this, just sitting next to an old man. The old man looked at the superstructure of Versailles, holding a sketch book in his hand and clutching a pencil. There was a sketch of Versailles on it, which was exquisite and attentive. The old man should be a folk expert with professional art level. I became interested in him and sat next to him for a long time. The old man ignored me and continued to finish his painting. And I just found the book about European architecture next to him! His paintings are marked with many architectural terms, and his standard French round characters are "eye-catching" although I can't understand them. His eyes are more and more fascinating, which makes people feel "eager to see". His eyes seem to penetrate the Palace of Versailles and thoroughly understand its contents, knowledge and even emotions. At present, he has been looking up at Versailles for more than 80 minutes. I seem to feel his thoughts and ideas. The old man is in the copy Palace of Versailles. He wants to feel this building that integrates the beautiful art of mankind and everything about Versailles. There is a suitcase beside the old man, and there is a ticket in his pocket with the departure time tonight-dear! In fact, this old man suddenly noticed Versailles on his return trip, because its charm made him sit down, slow down, think hard and feel the beautiful art. On the way home, my heart has already decided to sow a seed of thinking, and I must think hard and look at all the beautiful things in my future trip. Even if there is not enough time, even if it is just a small matter of dew flowing into the bud, it will also cause me to think. In the book "Three-body", the powerful three-body man was defeated by the earth people who were tens of thousands of years behind them because "human beings are thinking reeds, and no one can stop folding." So am I. Thinking always brings inspiration and strength. I hope that the old man can make me plant the seeds full of hope and thinking, and can break ground as soon as possible and grow slowly into a thinking tree.
