“..Such practices and beliefs, which interfere with happiness, are neither inevitable nor necessary; they evolved by chance, as a result of random responses to accidental conditions. But once they become part of the norms and habits of a culture, people assume that this is how things must be; they come to believe they have no other options.”

“Once people learned how to believe in something, that skill started spilling over to other parts of their lives, until they started believing they could change. Belief was the ingredient that made a reworked habit loop into a permanent behavior.”

“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.”

“The belief-transmission network of which we are a part cannot operate without a continuously replenished supply of people to do the transmitting, thus the belief that children are a source of happiness becomes a part of our cultural wisdom simply because the opposite belief unravels the fabric of any society that holds it.”

“It was like how people find other people to be in love with, all random and accidental and lucky.”

“One of the falsest of proverbs is that you must lie on the bed that you have made. The experience of life shows that people are constantly doing things which must lead to disaster, and yet by come chance manage to evade the result of their folly.”
