In Maxims and Reflections, Goethe wrote, "Tell me with whom you consort and I will tell you who you are; if I know how you spend your time, then I know what might become of you."
As I was doing the initial research for my forthcoming masterpiece of a book, about habit-formation, I tended to focus on strategies that I use as an individual.
I realized, however, that while it's easy to imagine myself operating in isolation, in fact, other people’s actions and habits exert tremendous influence on me, as mine do on them.
All the strategies of habit-formation deserve to be—and have been—the subject of entire books, but the Strategy of Other People is the strategy that’s hardest to distill into a single chapter. Our influence on each other’s habits is a vast subject. And it’s one of the most powerful, sometimes almost irresistible, strategies.
For instance, my husband, in particular, makes a big difference to my habits. In a phenomenon known as “health concordance,” couples’ health habits and statuses tend to merge over time. One partner’s health behaviors—habits related to sleep, eating, exercise, doctor visits, use of alcohol, cigarettes, and marijuana—influence those behaviors in a partner. If one partner has Type 2 diabetes, the other partner faces a significant increase in the risk of developing it, as well. If one partner gives up cigarettes or alcohol, the other is more likely to quit.
My husband's unwavering commitment to exercise has helped me stay dedicated. I also caught his habit of reading multiple books at one time, and buying books even when I have a huge pile I haven’t read yet. (Before we were married, I read one book at a time, and never allowed myself to acquire more than five unread books).
Also, some of my habits bothered him so much that I gave them up. For some reason, he objected to my snacking in bed. The things we do for love.
To quote another great thinker, in Letters from a Stoic, Seneca advised, "Associate with people who are likely to improve you." This turns out to be very effective, because we do so readily pick up habits -- good and bad -- from each other.
How about you? Can you think of times when you've caught a good or bad habit from someone around you? Or when someone has caught your habit? A few years ago, I dramatically changed my eating habits (that's a story for another day, and an example of the Strategy of the Lightning Bolt, but if you're curious, check out Gary Taubes's Why We Get Fat), and I've noticed that my change has led to changes in other people, as my habits rubbed off on them.
