The Power of Habit: Why We Do What We Do in Life and Business

My highlights and comments

'Andreasen wanted to know why these people had deviated from their usual patterns. What he discovered has become a pillar of modern marketing theory: People's buying habits are more likely to change when they go through a major life event. When someone gets married, for example, they're more likely to start buying a new type of coffee. When they move into a new house, they're more apt to purchase a different kind of cereal. When they get divorced, there's a higher chance they'll start buying different brands of beer. Consumers going through major life events often don't notice, or care, that their shopping patterns have shifted. However, retailers notice, and they care quite a bit.
"Changing residence, getting married or divorced, losing or changing a job, having someone enter or leave the household," Andreasen wrote, are life changes that make consumers more "vulnerable to intervention by marketers."' (Chapter 7)

Very often I used to buy food from restaurants, fast food restaurants, and delivery. When the COVID-19 pandemic started in El Salvador in March of 2020, I started to work exclusively from home. Also, El Salvador had mandatory quarantines. As a result of those major life events that affected the entire country (and the world!), I started to exclusively buy food from supermarkets and cook it myself! No more food from restaurants and delivery. That was extremely unlikely to happen without a major life event, since I used to work from the office, not from home, and I used to eat at the office from Monday through Friday. Even breakfast and dinner I sometimes used to buy it already cooked, and eat at restaurants often or order pizza now and then. My eating habits totally changed in a positive way, since I eat much healtier now! I even lost weight and I feel that I am eating very healthy.

"Question: Have you continued weighing yourself?
Tom: Every day." (Afterword)

I weigh myself every day, twice a day. I have noticed how during the COVID-19 pandemic I have lost weight. In March this year, if I remember correctly, I think I was weighing about 169 pounds and I may have even reached the 170 pounds at one point. Today I was weighing around 156 or 158 pounds. I have an analog scale. It may not be as precise as I wanted it to be. But it seems clear that I am below 160 pounds, getting closer to 155 and at this pace my goal is that this year, before December 31, 2020, my weight will be below 150 pounds. I still have to lose 20 pounds to have a healthy weight. I am still in the over weight category but definitely not obese. When I was weighing almost 170 pounds at the beginning of this pandemic, I was on the edge of obesity! Maybe one or two pounds away from officially fitting into the category of an obese person. That is NOT where I want to be. I believe if I maintain the habits and discipline that I already have, by the end of this year I will get closer to my healthy weight, which is about 135 pounds. To be more specific, before I turn 40 years old my goal is to weight below 135 pounds! That is a realistic goal I believe because I am about to turn 34 years old. I have 6 years to reach my goal. With the habits and discipline that I already have to eat healthy and exercise, I think I should be able to weight less than 135 pounds before I turn 40 years old! That is a SMART goal:

  • "Specific (simple, sensible, significant).
  • Measurable (meaningful, motivating).
  • Achievable (agreed, attainable).
  • Relevant (reasonable, realistic and resourced, results-based).
  • Time bound (time-based, time limited, time/cost limited, timely, time-sensitive)." (

On August 19, 2020, I weigh 150 pounds.
