Desire isn't binary. The fact that most single men don't take the action of writing deranged letters to their favourite female movie stars inviting them round for a quick shag, doesn't mean that they don't genuinely "want" to sleep with them. You can genuinely want something yet not get around to doing anything about or, or be in a position where it doesn't appear realistically within reach. By all means point out that they obviously don't want it ENOUGH, but we really don't need to start redefining the English language in order to make the point.
I have been into this affirmation stuff thinking for decades by now, long before anyone had heard about "The Secret" ...
The concept has been misused and misinterpreted many many times, and people have even made money from trashing it. But it works, it definitely works, and I have got it proved more times than I can count. I have learned that if you want to be or have something, you will probably get it if you only have the courage to go for it. You can always make up excuses, there are probably one million of them, but most of them are really nothing but excuses.
I don't know what post of mine the OP referred to above, but actually I agree. People often tell me that they want this and they want that, and when I say "why don't you just do it, then?" I am FLOODED by explanations and excuses, some good, and some really really bad.
But to go to the source of the problem, people often do not quite know what they really want. We have the recurring question here at the forum, something like this: "so guys, I am 24 years old and I have just started to play the piano. Do you think I have any chances to become a famous concert pianist? I learned La Campanella in a week and people say I am really good. What do you think?"
Here we get the standard bunch of replies: "Of course not, unless you did not start at the age of 3 you are lost, man" or "Of course, if you just put your mind into it, you can do whatever you want" or "how the h*ll are WE supposed to know, we have not even heard you play!"
I usually reply with No. 2, but at the same time ... well, if you really want to become a famous concert pianists, then you should not bother to hang on a stupid Internet forum, asking questions to a bunch of ignorant strangers. You should be far too occupied WORKING on your new career to have time to even be on the Internet, even less to ask about opinions from strangers.
Question is: what do you REALLY want in this case? Ok, so I want to be a famous pianist myself. Or rather, I would love to be on stage, dressed like a queen, and receive beautiful flowers while a big, roaring audience gives me standing ovations and fans gather at my feet, yelling for my attention, and critics write raving reviews about my talent and people at Pianostreet rank me as Leading Lady of the whole piano world. Yes, I want praise, I want to have nice dresses, I want to get lovely flowers and tons of flattering attention. I want to live my life at a truly magnificent Steinway D - we would look SO GOOD together! - and I want to socialize with interesting celebrities and life The Good Life in general and be a guest at David Letterman and ...
All right, you got it. I also want to master this wonderful music which I adore. But what about the dark side of fame, do I want that too? Do I want to practice day and night and sacrifice practically everything else I enjoy? Do I want to live half my life in impersonal hotel rooms and uncomfortable flights, do I want to sit there alone in the dark when the audience has gone home, do I want the difficult economical conditions, the mean critics, the creepy stalkers, the rough venues, the horror pianos, the conductors from hell, the stage fright, the tough competition, the pain in my hands? I know enough about the life of concert pianists to know that it is not that glamorous. That you could become the MOST FAMOUS of them all - still the majority of the world population won't know who you are, and/or not give a d*mn.
So the truth is that I don't want to become a famous pianist at all. I want to live a good life. I want ... to be happy. It is as simple as that. And I ALSO want to play and learn music pieces, but I have realized that I need nobody else's praise to do that. I am happy when I sit here in my own nice living room and learn something new, and that fame thing ... well, maybe I can get it in some other way then. Maybe I don't have to be on that stage, by the way. I can just as well sit in the audience and look good. I can buy flowers for myself.
This is a photo from my lving room, this is the reality in which I live. I play that piece, not very well, but if I want to hear a master's version I have it on a CD. So? If you "want" something, then investigate thoroughly what you REALLY want in this. You will most likely get what you want, if you just want it badly enough, and if you really know what it is.
