"Think And Grow Rich" is a book written by Napoleon Hill in 1937 about how to correctly change your mental framework about money. If you apply it to trading, the only reason traders lose money is emotion. If you take the emotion out of your trading, you can do well. The guy posting the falling safe probably never read it and hasn't made much trading, so he's venting.
Hill wrote this book after carefully studying how men of simple means created the great fortunes of our time, with particular attention paid to how Andrew Carnegie, who knew almost nothing about steel, became the wealthiest steel magnate in history.
The book became controversial, and the powers that be started to see his teachings as a threat, so after the first printing, a large chunk of the book was cut out by the publisher. Subsequent printings are all missing this section, so if you want to get the full benefit, it requires finding a copy printed in 1937-38, or you're missing the whole point.
If you're not into self-help, that's fine, but if you're a trader, I doubt anybody else is going to do it for you.
Happy Trading!
If you've ever tried selling products, especially books, it IS hard work. What Napoleon Hill's book shows you is how to work smart, along with working hard, not instead of it. It's how to get out of your own way.
