I generally listen to no more than 2 in one day. Often, the instructions with the Paraliminal will give you an idea of how many sessions to do. Some go on for more than a week and some are on an "as needed" basis.
If you have some goal lists for different areas of your life, it may be a little easier to find the balance for your own use of the Paraliminals. Using your specific goals will curb the tendency of letting one Paraliminal lead to another, to another, in an endless loop. Target goals can prevent that.
For me, I found that Self-Esteem was connected to Relationships, both were affected by Anxiety, which affected Health, which impacted Prosperity. I could see that the choices might sink me. So I did some top-level goal setting and some small immediate results targets (aimed towards the top level goals) and that helped hugely.
Also, as you use the Paraliminals more, I think you will probably intuit which would be most appropriate for your current needs.
Have fun being your true self.
