Way of the Turtle - its a great book

The best turtle told us how to make money in trading. What are the important ideas from the book?

(1) Even for best traders, only 30% trades are successful. 70% trades a wrong. Then the 30% trade's profit must be more than enough to cover the 70% of losses. Thus the concept that all big trends can not be missed. And can not exit too early.

(2) Every trade should only risk a small fix % of the total capital (eg. 2% for the turtle). When the % is up, cut loss no matter what. That is crucial for capital preservation.

(3) Enter trade whenever the entry signals are clear. Dont pick and choose which trade to enter. Over the long run, trader will lose out.

I believe these are the 3 principles hardest for me to swallow from this book.

But well ... it works that way. I cant argue otherwise at my own perils.
