I know this is the "wish card", or the 'yes', to a 'yes or no' question.
A wish just means you'll wish for something - doesn't mean you'll get it. You can spend your whole life wishing for things you don't have - and missing the pleasure in what you do actually have.
It's worth actually looking closely at the card. If you are working with the RW deck or a close clone, you'll see a flushed, slightly overweight man sitting in front of a row of cups, his arms folded across his chest.
His body-language says: you can't pass me. All this is mine and I'm not sharing.
His actual physical appearance talks of over-indulgence: his gaining weight, his flushed face.
I read the card as someone who *thinks* they have what they want because they have what they asked for - but who is smug and self-satisfied rather than actually happy. Few smug people are happy: what you THINK you want is not often what you actually want.
(I could say I want lots of money, but actually I want to be happy, and just think money might make me happy, is a nice example. I know a lot of rich unhappy folks.)
