The bulk of this book is about the restaurant discipline of mise-en-place, with lots of interviews and stories to illustrate the underlying principles. The back half then attempts to apply these to modern office work and advocates a particular system (in the vein of GTD). He's a little too indulgent of hustle culture and the frankly abusive environment that seems to be the norm of many kitchens. Overall this is excellent food for thought when it comes to evaluating your own work systems but I'm not entirely persuaded that his Work Clean method is obviously superior.
