Thank you Norbert Martin and vita-man for your input. I guess it is right to give my unconscious mind a break - and for me to see or feel the difference.
What's bugging me though, is that I want to listen to the Memory Supercharger for a week (which I suppose is 7 days not a 5 day working week), and whilst I am at it I want to also listen to Personal Genius (for a whole week). After that week I want to listen to You Deserve It and Peak Performance.
So the thing here is, do I take a break after PG and MS before I move on to YDI and PP?
You guys are great. Thanks for your help that I know is coming.
