I'm not very big on "The Secret" - the idea that you send messages out to the universe with your intent and then it works to provide those things for you. I just can't get over the relationship between hard work and success. I don't see messages sent into the universe having much to do with it.
There are places in Think and Grow Rich where Napoleon Hill does seem to hint at "The Secret." Do you think in he is talking about the same thing? Nevertheless, Napoleon Hill speaks enough of hard work and determination that I don't think he falls into the same realm as the hucksters telling people that all they have to do is put their desire out there and the universe will provide.
