Neale Donald Walsch, in Conversations with God, stated something to the effect you cannot get what you want because it produces the experiences of wanting.
so we must get to the feeling of having it, hence the suggestion to get into that car, house, around people doing the things you want to be doing so you can imagine and feel like you are doing it.
Then you will.
I've found it to be true, and been able to change many things using Faith.
With faith (God) we can do anything.
