That reminds me of the age old problem of
knowing what you want.

Or what you really mean is what is your core
desire? Many people will just say *More money*,
but this is too general and not specific enough.

Ask yourself if I had more money what would this
give me? For example a bigger house/car, Ok if
you had more money and a bigger house/car what
would that give you that you havn't got now?

Maybe more freedom, more security, So again,
what would this give you that you havn't got now?
And you keep going until you may end up with
something like I want more significance in my life,
which would make me feel more powerful and respected.

So what you really want is more is more significance
in your life, and you feel money is your route to
that end.

Marketers love to feed this feeling and will keep
supplying your wants to move you closer to your dream.
But really its an illusion, and once attained you will
crave more and more.

So your focus has to be what do I really want to *feel*
that these external material objects will provide to me?

Usually its something like happiness, or love which
costs nothing and you can choose them right now!
