It's too early for me to say what insights or "Aha" moments I had, but I can tell what chapters like liked(as in touched me). I got the book on 20th Oct & just finished reading Part 1 yesterday. I plan to re-read Part 1 to 'internalize' and apply the concepts(this time very very slowly).
The chapters I like were Intelligence,Power,Authority,Courage,Truth,Love & Oneness(in order of how it touched me - at this stage I would like to call it an aerial-survey of Part 1 from my perspective). I liked the "Growth Blitzing" concept the most.
My secret: Deep inside I know that Truth should have been the 1st one
