What a goldmine of a book! One of the best books not only on the topic of concentration, but success in general. Came out before Think and Grow Rich and it's hard to believe some of the ideas in TAGR haven't been taken from here. Maybe the people Napoleon Hill interviewed read this book.
But in any case, this is a MUST READ. Don't disregard its simplicity or brevity, it could have an important impact in your life if put into action.
