How many times, and in how many ways, can we "discover" or "invent" the radical concept that doing well what you do every day tends to produce success? For people who go to sleep at night with phrases like "market share" and "profit margin" dancing about in their heads, this book may seem helpful. One cannot help but wonder, however, what would happen to quality and productivity if the time, money, effort, and energy devoted to ingesting this sort of thing were instead pumped into attending to the job at hand. One saving grace: There are people who still don't get it, and this book just might make a dent in their thick skulls.
