This is from an American point of view, so some of the things in here weren't relevant to me.
There wasn't much to be learned here either for me as I've read most of the things in other books.
When I bought this book, I knew nothing about it, I bought it because of the title.
After buying it though, I quickly found out that it was first printed in 1905, so it's severely outdated and only some of it was transferable.
