I'm getting a little tired of authors repackaging the same time management and focus techniques as other authors, collected, re-written and then with some sort of marketing twist (ie. 18 Minutes) and then somehow marketing the hell out of the book and getting some quotes from some influential and prominent pundits. It's becoming an industry problem.
Sure, part of my annoyance is that I manage to feed this trend by my own insecurities and the belief that maybe there will be one useful thing here that might make me a lot more productive. My frustration is partly at my own disappointment in myself and that I am such a gullible part of the hype cycle.
