There are a few key points to starting manifesting/creating abundance. One of them is the ability not to focus on the "lack of". Ignore it. Completely.

And the next is similar and says - don't expect results the second after intending/creating it. Don't even go about looking for it. Intend it, let it go and be happy when it comes along. Trust the process.

There's something to what your coach told you "She said it is probably working but I dont realize it is working." That may give a focus of letting go and trusting the process.

Prosperity might be the paraliminal you're after. I also like passive things that works for me but beeing a creator/manifester takes a little more than paraliminal tapes IMHO. If they don't wipe away all limiting beliefs.
