Query: I DOUBLED MY EFFECTIVENESS WITH THE SUPERSELF STRATEGIES!

The strategies on this tape really work! Before Superself (I also own the book), I found myself very efficient, busy, busy, busy but not as effectve as I would have liked to be. I now get more done in half the time. I am also more calm and relaxed during tense periods where I used to lose my cool. Superself, the tape and the book should be a part of anyones personal development library.
