Although I did highlight many passages in this book, I found most of the useful material to be the same as that which I've read elsewhere. It served more as an affirmation of my existing motivational habits than a source of new ideas. Perhaps the material would have felt revelationary to me if I had read this book when it was first published in the 90s (which I wouldn't have, since I was only a little kid back then) but the updates that have been made for this third edition just weren't enough to unstick it from that era. This might still be a good motivational read for someone from Gen X or older, who has never tried reading anything like it before, but it didn't do the trick for Millennial me.
