I’ve just started reading Focus, by Daniel Coleman. If a book may be judged by the degree and speed with which it raises one’s blood pressure, I have to say this is pretty good value. I’m only 3% in, according to my Kindle status bar, and already I’ve found three things to disagree with. And let’s not forget that that 3% includes all the “prelims”, i.e. title and copyright pages, table of contents, and so on.
