Query: Old and simple, but winning ways

I've nearly finished the book, and the simple ways of trading is something I think will be valuable to me in my future trading. Of course you do not rely solely on Livermores ways - the economy and the stock market is more complex today than it appeares to have been then. But when you make your educated guesses, I think his lowbrow way of letting the price action prove or disapprove the thinking, and then pyramiding up (on longs) or down (on shorts) is actually a nice way of letting yourself into a position. I do not think you have to do his extreme concentration on one or two stocks. As long as you can keep up with the action, a bigger number of stocks can keep you away from his boom/bust experiences thru diversification.
