An hour a day focusing on your one passion makes the difference.
Have you used New History Generator?
You don't need to use any Paraliminal for a week. With ADHD I suggest you try alternating it more.
It does depend on your actual goals which Paraliminal you could use. I can See a spot for Belief, New Options Generator, Peak Performance, Automatic Pilot, Self-Esteem Supercharger, Personal Genius. Letts sidestep the ADHD stuff for a moment and establish a goal. What would you like to be doing in the future. How would you like to be acting, behaving in the future? If you could do one thing now that would move you one notch in that direction what would that thing you need to do be? Then look at the Paraliminals and select the one that is most appropriate for giving you leverage.
Now for ADHD
If you really want a Non Drug approach to performing better with ADHD, hop over to the Spring Forest Qigong forum and find out more about that. That has active meditation which helps to develop concentration and doing it 30 to 60 minutes a day requires a discipline. It's easy and has a number of other benefits.
It isn't a sitting on you butt waiting for a CD to fix me approach to it. and it sounds like you're looking for more than that too.
