Just got to Chapter 8.
It reads pretty well and I'm trying to keep an open mind about it. The first part tends to lean more toward goal-setting/dreaming big/conquering fear/etc... basically stuff that you read all the time in personal development/self-help books/articles.
I just finished the second part (chaps. 5-7) which deals primarily with time management and simplification, so you don't get bogged down with stupid sh*t that other people can do. That's given me some food for thought, actually. Still got about 70% of the book to go.
In your particular case, I imagine much of what I've read up to now is old news to you. You might want to read some of Chapter 8 (or later in the book) first and then decide whether to read the rest.
I'll probably read the whole thing through.
