Book Review: The Power of Habit
During Ramadan, I built two habits I had been striving for:
Instead of snacking - granted I couldn't eat even if I wanted to - I took a few breaks at work throughout the day to take 10-15 minute walks. I would also go on walks before iftaar. Even though I would be exhausted and hungry before my walk, I' would come back refreshed and energized.
I ate salads most days for iftaar - not for healthy or weight loss purposes - but because I really wanted to eat a salad. I also almost completely stopped drinking soda.Â
Soon after Ramadan ended, however, I fell back into my normal pattern of snacking at my desk, eating carbs/heavy food, and drinking soda. I picked up running 3-4 miles multiple times a week back up, but I stopped going on walks.
How did this happen? I struggled with how quickly my willpower fell short of expectations, and then, I stumbled upon this book - The Power of Habit - at Barnes and Noble.
I've read reviews raving about it for years, but never picked it up. I felt like making new habits was common sense. Stop doing what you're trying to give up. Replace it with what you are striving to do instead. But if that's the case, then why did I find it so hard to make better habits? When I finally did, why did I relapse so quickly back into my bad habits?  What was I doing wrong?Â
When I picked up this book, I was immediately drawn in by the story of a women who quit smoking, lost 60 lbs and became a marathon runner. I was fascinated by how scientists conducted brain scans and discovered how her neural activity as a whole changed after her habits changed - and the impact this brain activity has on we attempt to make new habits. The book follows this pattern throughout. It gives practical advice on reshaping an individual's or an organizations' habits based on real life stories backed by scientific research and psychology studies.
In addition to learning a new approach to changing habits, I've learned another important fact that I will always try to remember - once a habit is truly formed, it never really goes away. It can only be masked. This is a scary, and it's something I'm going to try to remember when I debate if I should grab a Caramel Machiatto on the way to my desk.
Overall, the Power of Habit was engaging and thought-provoking  (which my coworkers can attest to since I would sneak in reading breaks at work and constantly talk about what I learned) and is a must-read for anyone interested in understanding human behavior, societal/corporate patterns, and how to change their habits. Below are my notes from the book for anyone interested in a quick overview of the key facts that stood out to me. The book's anecdotes and psychological studies that explain these facts are what truly brings them to life, so do not use this as a substitute to reading the book.Â

More than 40% of the actions people perform each day aren't actual decisions, but habits.
Part 1: The Habits of Individuals
Chapter 1: The Habit Loop
The brain layers closest to your scalp are the most recent additions from an evolutionary perspective and it's where your most complex thinking occurs.
Deeper inside the brain and closer to the brain stem - where the brain meets the spinal cord - are older, more primitive structures. They control automatic behaviors, such as breathing, swallowing, etc.
Toward the center of the skull is a golf ball sized lump of tissue that is similar to what you might find inside of a fish. This is the basal ganglia.Â
Rat-maze-chocolate experiment indicated that the basal ganglia was central to recalling patterns and acting on them. Brain converts a sequence of actions into an automatic routine.
Habits emerge because the brain is constantly looking for ways to save effort, and turn a routine into habit.
The habit loop is cue, routine, reward.
When a habit emerges, the brain stops fully participating in decision making.Â
Habits never really disappear. They are encoded into new structures of our brains.
People whose basal ganglia are damaged by injury or disease often become mentally paralyzed. They have trouble performing basic activities.Â
Chapter 2: The Craving Brain, How to Create New Habits
Craving is what makes cues and rewards work. Craving is what powers the habit loop.Â
Studies of people who have successfully started new exercise routines show they are more likely to stick with a workout plan if they chose a specific cue (running as soon as they get home) and a clear reward (beer with dinner). But that's still not enough.
Monkey habit loop experiment: For those monkeys who hadn't developed a strong habit, the distractions worked. Once a monkey had developed a habit - once it's brain anticipated the reward - the distractions held no allure. . . The anticipation and sense of craving was so overwhelming tat the monkey stated glued to their screens, the same way a gambler will play slots long after he's lost his winnings.
This explains why habits are so powerful: Habits create neurological cravings. Most of the time, these cravings emerge so gradually that we're not really aware they exist, so we're often blind to their influence. But as we associate cues with certain rewards, a subconscious craving emerges in our brains that starts the habit loop spinning.
There is nothing programmed into our brains that makes us see a box of doughnuts and automatically want a sugary treat. But once our brain learns that a doughnut box contains yummy sugar and other carbs, it will start anticipating a sugar high. Our brains will push us toward the box. Then, if we don't eat the doughnut, we'll find disappointed.
 Cue and reward aren't enough. Only when your brain starts expecting the reward - craving it - will it turn into an automatic behaviorÂ
Three rules: (1) Find a simple and obvious cue. (2) Clearly define the rewards. (3)Â Allow yourself to anticipate the reward. Create a craving.Â
Chapter 3: The Golden Rule of Habit Change, Why Transformation Occurs
To change a habit, you must keep the old cue, deliver the old reward, and change the habit.Â
Alcoholics only permanently changed once they learned new routines that drew on the old triggers and provided familiar relief. New ways for dealing with life.Â
First step in habit reversal training is asking patients to describe what triggers their habitual behaviors.
The brain can be reprogrammed. You just have to be deliberate about it.
Change occurs among other people. It seems real when we can see it in other people's eyes. People must believe that change is feasible. Belief is easier when it occurs within a community.
Part 2: The Habits of Successful Organizations
Chapter 4: Keystone Habits, or the Ballad of Paul O Neill, Which Habits Matter Most
Some habits matter more than others. They help other habits flourish by creating new structures, and they establish cultures where change becomes contagious.
Examples: Alcoa, Michael Phelps, gay rights organizations
Small wins fuel transformative changes by leveraging tiny advantages into patterns that convince people that bigger achievements are within reach.
Chapter 5: Starbucks and The Habit of Success, When Willpower Becomes Automatic
Self-discipline has a bigger effect on academic performance than does intellectual talent.
Cookie vs radish experiment: Willpower isn't just a skill. it's a muscle, like the muscles in your arms or legs, and it gets tired as it works harder, so there's less power left over for other things.
Money management and exercising program: Once willpower became stronger, it touched everything. People get better at regulating their impulses. Once you've gotten into that willpower groove, your brain is practiced at helping you focus on a goal.Â
This is how willpower becomes a habit: by choosing a certain behavior ahead of time and then following that routine when an inflection (temptation/pain ) arrives
If you tell people that they have what it takes to succeed, they'll prove you right.
Cookie, nice vs rude, puzzle experiment: When people are asked to do something that takes self-control, if they think they are doing it for personal reasons - if they feel like it's a choice or something they enjoy because it helps someone else - it's much less taxing. If they feel like they have no autonomy, if they are just following orders, their willpower muscles get tired much faster.
Chapter 6: The Power of a Crisis: How Leaders Create Habits Through Accident and Design
Good leaders seize crises to remake organizational habits.
Examples: Underground London Station fire, Rhode Island Hospital, NASA
Chapter 7: How Target Knows What You Want Before You Do, When Companies Predict (and Manipulate) Habits
Our brains crave familiarity in music. Radio listeners didn't want to make a conscious decision each time they were preset end with a new song. Their brains wanted to follow a habit.Â
Examples: Hey Ya! and Song sandwiching. Organ meat campaign in 1940s
Whether selling a song, a new food, or a new crib, the lesson is the same: If you dress a new something in old habits, it's easier for the public to accept it.
Part 3: The Habits of Societies
Chapter 8: Saddleback Church and the Montgomery Bus Boycott: How Movements Happen
A movement starts because of the social habits of friendship and the strong ties between close acquaintances.Â
It grows because of the habits of a community, and the weak ties that hold neighborhoods and clans together. Peer pressure!
It endures because a movement's leaders give participants new habits that create a fresh sense of identity and feeling of ownership.
Chapter 9: The Neurology of Free Will, Are We Responsible For Our Habits?
We were particularly interested in looking at the brain systems involved in habits and addictions. What we found was that, neurologically speaking, pathological gamblers got more excited about winning. When the symbols lined up, even though they didn't actually win any money, the areas in their brains related emotion and reward were much more active than non-pathological gamblers. But what was really interesting were the near misses. To pathological gamblers, near misses looked like wins. Their brains reacted almost the same way. But to a non-pathological gambler, a near misses was like a loss. People without a gambling problem were better at a recognizing that a near miss means you still lose.Â
