Query: An extermely overpriced book!

After I had done with this book, just realized ... there're many familiar facts/infos can be found on other similar trading books. The only thing I can conclude is ... The author just too inexperience in volatile trading world not to say publishing a book to teach others... (trying to cover his lost in stocks?) as we can see... he himself can't even control and handle his emotion on down days... see page 224 "I find that when I hold a volatile stock overnight... trouble sleeping. I toss and turn all night worrying...." see page223"irrational thoughts were entering my head. I was angry. My brother was in the room and I was even mad at him..."Well, all these just happened few months before the book was published. How many novice investers had incurred a lost in stock market after reading this book? I wonder... My advice, son .... learn how to drive safely before you start teaching others! from A stock market veteran
