Thanks to two brilliant authors, as a first born Gen-Xer (1961), I now understand why society treats my cohorts and I the way they do. This book is nothing short of genius. Strauss and Howe have helped me on a personal level and business level. Personally I completely understand my place in society today and the future. Furthermore I can alter that future if I choose too. On a business level, for marketing purposes, I now have a solid knowledge of the living generations. And the authors glimpse into the future is a tool I can use to help guide my business in the coming years.Like Harry S. Dent, Ken Dychtwald and Larry Williams, Strauss and Howe support their future theories with rock solid evidence from the past. Over and over again their theories are validated. I can't thank them enough for the peace of mind their work has given me.I'm really looking forward to reading their book, "The Fourth Turning".
