Atomic Habits

* Dopamine is not the only chemical that influences your habits.

Every behavior involves multiple brain regions and

neurochemicals, and anyone who claims that “habits are all about

dopamine” is skipping over major portions of the process. It is just

one of the important role players in habit formation. However, I

will single out the dopamine circuit in this chapter because it

provides a window into the biological underpinnings of desire,

craving, and motivation that are behind every habit.
