Little point in spending more time listening to paraliminals and holosync all day. You still need to go out to the world to integrate the experiences from them in your outer life. The paraliminals are more useful if you have a specific goal you want to work on, so often one a day is enough to perhaps 3, more than that I think the individual needs to consider that they may be doubting the good work that the paraliminal can do and undermining the outcome with self doubt. More is not necessarily better.
