Charles Duhigg,

“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.”
