Experiments have shown that almost all habitual cues fit into one of five categories: Location Time Emotional state Other people Immediately preceding action

the cue for this routine? Is it hunger? Boredom? Low blood sugar? That you need a break before plunging into another task? And what’s the reward? The cookie itself? The change of scenery? The temporary distraction? Socializing with colleagues? Or the burst of energy that comes from that blast of sugar? To figure this out, you’ll need to do a little

when researchers studied an incoming class of cadets at West Point, they measured their grade point averages, physical aptitude, military abilities, and self-discipline. When they correlated those factors with whether students dropped out or graduated, however, they found that all of them mattered less than a factor researchers referred to as

By focusing on one pattern—what is known as a “keystone habit”—

Small wins are exactly what they sound like, and are part of how keystone habits create widespread changes. A huge body of research has shown that small wins have enormous power, an influence disproportionate to the accomplishments of the victories themselves. “Small wins are a steady application of a small advantage,” one Cornell professor wrote

He created a craving. And that craving, it turns out, is what makes cues and rewards work. That craving is what powers the habit loop.

Lisa had focused on changing just one habit—smoking—at first. Everyone in the study had gone through a similar process. By focusing on one pattern—what is known as a “keystone habit”—Lisa had taught herself how to reprogram the other routines in her life, as well.

THE FRAMEWORK: • Identify the routine • Experiment with rewards • Isolate the cue • Have a plan

Studies of people who have successfully started new exercise routines, for instance, show they are more likely to stick with a workout plan if they choose a specific cue, such as running as soon as they get home from work, and a clear reward, such as a beer or an evening of guilt-free television.13
