In my experience with the paraliminals I found for exercising is Peak Performance it does indeed help quite a bit. But I also found that my exercise program before was kind of non motivating so I switched to Step Rebook with exercises from Gin Millar and then my drive and motivation went off the wall.
Currently I can waste a lot of time on my computer looking at weather reports, stock quotes and this could last all night. I could have be very productive doing other things and this is what was recomended to me Break the Habit and New Behavior Generator.
As for confidence one must challange and change beliefs of ones self. So I would go with Belief and Automatic Pilot and Self Esteem SuperCharger.
