As it was written in 2002, there was a lot of this book that was very outdated now in 2021--I found the parts about the internet and email especially funny.
The best part of this book in my opinion was the beginning when it explained how to write a sound bite/elevator pitch. I think the advice of writing basically what's on your mind, taking a step back and circling the most important words, ranking them, and re-writing is a really helpful exercise. Same with the exercise in the headline chapter which adds another aspect of also underlining the unnecessary words and re-writing without those.
the tl;dr of this book was know your shit, be charismatic, and talk to as many people as physically possible and hope they help you
