Let's knock this one for dead right now.
I got rather upset a few weeks ago when a client offered me a lot of money to show her how to access "the hidden jobs market". I was upset for two reasons. Firstly, she clearly felt the reason for her continuing underemployment was the existence of some sort of conspiracy which she was not yet privy to. The second was that she felt that I knew all about it and wasn't telling her, and needed to be bought to do so.
Just because you can't see something it does not mean it is hidden. There is only one secret and I'll tell you it at the end of this article.
