Im expereincing my own challenges in a different area, visualizing, but from what I have had success with and learned the most effective way to use affirmations is by recording your own voice in the third person, "you are wealth, you are joy, you are abundance", and listen to it over and over during power naps or sleep, pretty much what holosync does, but I learn in third person it has more of an impact and less resistance, whereas when you say "I am wealth, I abundance" there might be conscious resistance.
I am going to start a post with problems I am having.
