Since my childhood, I always believed the things in the book were right. Now I think reading books without a brain to judge is really useless.

  Some people can write excellent books, but I’m even hard to understand them. There’re so many books all over the world. Even you can read one book per six minutes without sleeping for one hundred years, the number will be 8,760,000, which is even no more than half the number of books in Library of Congress, so what’re you going to do?

  Books are written by people, you’re people too, so you need to have your own brain to judge the books, read useful books, abandon books of no use. How to judge it? Only by your own brain.

You can own nothing in the world, but you must own your own brain to judge the world. Don’t let other people make yourself lost, even they’re celebrities.

  If you use your own brain to judge books ,then you’ll find useful books all over the world aren’t so much. Even useful books have things of no use, you can abandon them too, finally you’ll find books you can read not so much. Books are just like sands, good books are gold in sands, if you know to fossick, you’ll find there isn’t much gold as you think.

  If you don’t believe them, or think they’re not well enough, then you can write things to correct or improve them, which will become your own books, no matter they’re social science or natural science.
