Negative Positive
Title: Does it work?
Review: All the reviews here give an opinion on whether it is a good read. No one has commented what impact the 15 day plan has had on them. While I have just finished the book and haven't done the formal program, I can say that I have done parts previous to this and haven't noticed any improvements in mental competency. "How to think like Leonardo DeVinci" seems a better plan in this regard.
Is the review positive or negative?
