James Clear’s book is research packed, evidence based, and full of concrete and actionable ways to improve habits and reach goals. He defines atomic habits as, “a regular practice or routine that is not only small and easy to do, but also the source of incredible power; a component of the system of compound growth.” (p. 27). Clear’s 4 Laws of Behavior Change focus on creating a system of processes that make it easy to achieve the results you want.
