Your review actually helped put words to my nebulous thoughts about the book, Wealth Can't Wait.
My first ever BP podcast I listened to was show 226 with David Osborn. In that show he had so much energy and what he was saying seemed to make sense. I too bought his book back in June. It took me about a month or more to get through the whole thing. I agree that there was definitely a lot of filler and empty space and I was surprised at how many small chapters there were (that's not necessarily a bad thing). The quotes scattered throughout each chapter started to become distracting and I ended up not even reading them because they were only two lines away from the emboldened quote. While I was reading it I remember later in the day trying to tell my wife what I had learned and read. I couldn't even really remember anything specific and had to go back to the book and skim over it.
After I finished the book I felt the same way. About a week later I went back over the contents page to see what I even read because I couldn't really remember. For a book title talking about wealth and with the idea that it was supposed to help you get there it didn't really give any specifics on how to do it per se. There was a lot of generalizations, have better thinking, have better habits, etc. I think those things in of themselves are good though. Scott Trench actually talked about this in Podcast 223 that many of the books that he's read on wealth, like Rich Dad, Poor Dad, don't really tell you how to get there, which is why he wrote Set for Life, which that statement alone is why I have his book on order.
I read Millionaire Teacher by Andrew Hallam 2 weeks ago and I'm still thinking and reviewing the things over in my head about what he discussed in that book. Nothing like that happened with Osborn's, sadly. No slam on David, maybe that book just wasn't for me.
I agree with your advice at the end.
