“Most economists are accustomed to treating companies as idyllic places where everyone is devoted to a common goal: making as much money as possible. In the real world, that’s not how things work at all. Companies aren’t big happy families where everyone plays together nicely. Rather, most workplaces are made up of fiefdoms where executives compete for power and credit, often in hidden skirmishes that make their own performances appear superior and their rivals’ seem worse. Divisions compete for resources and sabotage each other to steal glory. Bosses pit their subordinates against one another so that no one can mount a coup.Companies aren’t families. They’re battlefields in a civil war.Yet despite this capacity for internecine warfare, most companies roll along relatively peacefully, year after year, because they have routines – habits – that create truces that allow everyone to set aside their rivalries long enough to get a day’s work done.”

“Companies aren’t families. They’re battlefields in a civil war.”

“Once you know a habit exists, you have the responsibility to change it . . . others have done so . . . That, in some ways, is the point of this book. Perhaps a sleep-walking murderer can plausibly argue that he wasn’t aware of his habit, and so he doesn’t bear responsibility for his crime, but almost all of the other patterns that exist in most people’s lives — how we eat and sleep and talk to our kids, how we unthinkingly spend our time, attention and money — those are habits that we know exist. And once you understand that habits can change, you have the freedom and the responsibility to remake them. Once you understand that habits can be rebuilt, the power of habit becomes easier to grasp and the only option left is to get to work.”

“Typically, people who exercise, start eating better and becoming more productive at work. They smoke less and show more patience with colleagues and family. They use their credit cards less frequently and say they feel less stressed. Exercise is a keystone habit that triggers widespread change.”

“Every habit, no matter its complexity, is malleable......however, to modify a habit, you must decide to change it. You must consciously accept the hard work of identifying the cues and rewards that drive the habits' routines, and find alternatives. You must know you have control and be self-conscious enough to use it.”

“Bureaucrats and politicians, rather than making decisions, were responding to cues with automatic routines in order to get rewards such as promotions or reelection.”

“I love Paul O'Neill, but you could not pay me enough to work for him again" one official told me. "the man has never encountered an answer he can't turn into another twenty hours of work.”
