Useful, but minimal. It's not accurate to say that. If used well, the effect will be great. There is no benefit in constantly "reading" famous quotes. The key is to do the above. The Analects of Confucius can also be regarded as famous quotes! But it is useless just to read it, but it will be great if you use it. Half of Zhao Pu's Analects governs the world, whether you think it is awesome or not. Nowadays, many people say that the so-called famous quotes are poisonous chicken soup. It always makes people think of thousands of roads at night and wake up during the day to take the same road. Little do we know that these famous quotes were summed up by predecessors based on their own lessons and experiences. They apply to ancient and modern times. How could they be useless?
What you see on paper will eventually make you realize it is shallow, but you know that you have to do this! Whether it is of any use is like a person knowing whether drinking water is cold or warm!
