I am so glad I've found this. I originally read the book when I was a teenager. I don't know the published date of the book, but I'm guessing 1960's. Anyway, this book has stuck with me all these years (over 20 yrs). I still apply the principles on an almost daily basis. I have longed for years to find this book again. Guess that's the GMC working!
