Query: still the best trading book after all these years

I know the book was old, published more than 20 years ago. However, the trading advice that the author gave was still relevent, after all these years.I am sure you probably heard this sentence, and I may not say it with the exact wording, it is something like " in wall street, the more things changed, the more things remain the same". This sentence is probably more than 100 years old.We have all the fancy things coming out since the book published: the internet, the day trading, the new trading methodologies, etc. however, the real trading methodology along with advice for trading psychology that can stand all the test remain the same, and those are written in this book.if you really serious about trading, buy this book and read it at least five times. You will get a lot from it. I can guarantee you that.
