If you're looking for pure strategy content, there's probably better material to spend your time on. Not that it's not there. And I think a lot of NL players can benefit from occasionally thinking about combinatorics and hands the way a limit player does. But if you're struggling with motivation and want some inspiration to work harder, this is definitely worthwhile.
The real inspiration for me, though, doesn't come so much from the book as from Paul himself and people like him. Some people just seem to get so much stuff done, and I used to feel a lot like I just didn't get a whole lot accomplished in a week. There's a guy like that in my office. He puts in more hours at work than most others, but somehow he also has time to rebuild parts of his house, exercise 3-4 times a week (including maintaining a very solid quality in his squash game - guy's 53 and still barely breaks a sweat when playing me. Bastard.), take care of his sailing boat and actually go on trips with it, has a wife and kid, a private little business on the side, a healthy social life, etc. And I used to feel like I barely had time to do my 40 hours of work and play some poker now and then on top of that.
See, a lot of time just get swallowed by nonsense, and the lion's share of that nonsense (for me) has to do with not feeling motivated enough to do something more productive with my time. So I end up watching TV or playing video games or whatever. Seeing what others manage to do with - presumably - the same length of week as I operate on is a good way for me to get cracking on stuff.
That said, my comment that you quoted was aimed more at the quality of the writing than of the content. It's actually a good read, in terms of writing quality, something that - sadly - most poker books aren't. In fact, most of them suck which makes my putting it at #2 sound facetious, but I really did enjoy it.
