I receieved self-esteem supercharger a few weeks ago and when I tried it the first time, I was consciously following the exercises for the right voice. Afterwards I felt it didn't work. I tried again and didn't see anything, so I gave up on it and went to use some other paraliminals.
However upon reading about your success Tore, I felt like trying the sleeplearning thing out. I had my headphones hooked up to my computer so I could set the sleeplearning track to repeat for 2hours, and then stop. So I drifted off to sleep while having it playing and the next day I woke up and felt different. I noticed that I pretty much had better self esteem, I wasn't able to feel down about myself and I just felt more in control, felt assertive. I tried it again that night, and while I only listened to it repeat 2 or 3 times(didn't feel like keeping the headphones on), the day after that I had even more self-esteem, it was like being near-invincible.
So for me the best way I've found to use the paraliminals is to not try to consciously pay attention to the voices, just to let it play. Even mind wandering doesn't seem to adversely affect the effects.
I'm just surprised that these paraliminals can work so quickly. I mean I can just listen to something like new history generator one night and the next day any past event that was bothering me I'll barely care about anymore, its great. Not to mention they're much more permanent than other affirmation/subliminal etc. things I've tried.
