The Secret is just the latest in a long line of Law of Attraction books that have been published through the years. I've read most of them, this one is a huge seller and made the author a millionaire because of the way it has been marketed. And it's a cynical marketing ploy too, and ruthless in its determination to be unopposed by any dissenting voices.
When I first heard about the LOA (Law of Attraction) I truly believed I had found the answer to everything and totally believed in its validity, only to look around many years later and see that nothing had actually changed. I didn't manifest the things I believed I would and don't know anyone else who has done so either. One friend who was singing the praises of The Secret when he first read it two years ago, has now given it away, completely disillusioned and feeling worse than he did before he read it and started following its 'advice'.
When all the affirmations, visualising, asking, believing, etc, doesn't work, or only in very limited or small ways, then the person who had grasped onto what seemed like the answer to their prayers, ends up feeling betrayed and without the false hope they had been given by this money-making spinner for the people selling it to gullible and vulnerable people, who, by their purchasing of the book, the CD, the DVD, the follow up books about what to do when it doesn't work or things go wrong(!) are putting money into the bank accounts of the people responsible for this 'spiritual marketing' as it is known in the trade.
When I see people unhappy because they believed in 'The Secret' only to find out much further down the line that it never delivered, that they never got richer, didn't look younger, didn't get the love interest they wanted, then it makes me want to warn others not to be sucked into it through them giving even more money to already extremely wealthy people. And make no mistake, when it doesn't work out how you believed it would, then they will tell you that you have done something wrong, or you must have blocks somewhere in your subconscious that need removing, (you can then buy more books to 'help' with this) or you need chakra clearing, (more books, and CDs too to buy!) or it must be that you need to love yourself more, because you can't love yourself properly or it would work for you.
Then you get told that you need to stop wanting anything and be 'spiritual' instead and believe that you have it all already, because once you get to that stage then you will be so content that you will realise that you have all you want already and won't need any more, because if you continue to want things, or conditions, then you just continue attracting more things or conditions to want, therefore you mustn't actually want anything! And so it goes on. I could say more and believe me I have long experience of dealing with these kind of people so I know what I'm talking about, but knowing how they operate, this would just get removed, as they are very protective of their money spinner and try to stop anyone from questioning it.
Just believe in yourself and try to think positive thoughts, (worrying unduly about anything doesn't actually change whatever it is you're worrying about) building up self-confidence and loving yourself truly and looking for anything at all you have to be grateful for, no matter how small, is the best advice I can give you, and I'm not charging anyone anything for saying that, or spinning it out into a whole book and marketing it in such a way that people will be sucked into buying it and making me very rich as a result of appearing to answer a need in people who are struggling.
