In a universe that seems to be more pliable than conventional thought might have us believe, there is no harm in intent and visualization. Even if there is no universe 'conspiring on your behalf' (there probably really is though) then those intentions and visualizations at least help you to focus on the end goal.
I was listening to the audiobook 'infinite possibilities' by Mike Dooley which I think is very much like 'the secret' of which I have not read, and he said something that stood out to me. This is paraphrased because I don't have the actual book....
{Either money is good and you want more of it, or money is bad and you want to avoid it} If you're thinking money is the root of all evil then guess what, you're probably not going to be inclined to get more of it than you need to live. If you think money is good and you can do things you like with it then you will probably try to get more of it.
In that sense people do want to be rich or want to be poor. I agree that money is often connected with bad ideas, bad actions and bad people, but the reality is that most of us have, however tacitly, agreed to live in a 'civilized' fashion where we buy things instead of making or raising them ourselves. As such we must as well dive in head long, at least until the eventual collapse, when we revert to feral behavior. I have begun to do intentioned visualizations each day because you know what? It really can't harm anything right and frankly it is limiting to deny something that we don't really know is true or not, and is maybe unprovable.
Also what AH said about your self image is mega ultra important. You are to a great extent what you choose to be. Most of us walk around as packaged identities unconsciously agreeing to view others as their packaged identities as long as they agree to view us as what we think we are. So make yourself whatever you want to be.
The naysayers here are the people who claim flight, or space travel is impossible. The people like AH are the people who invented flight and space travel. Pick which one you'd like to be. Whatever else their faults, they at least made it happen!
