It’s the new year transition, the line between our last year’s self and our hoped-for healthier, happier, and more productive 2020 self. To become that new self, we know what to do. We know that a full night’s sleep boosts our alertness, energy, and mood. We know that exercise lessens depression and anxiety, sculpts our bodies, and strengthens our hearts and minds. We know that what we put into our bodies—junk food or balanced nutrition, addictive substances or clean air—affects our health and longevity. Alas, as T. S. Eliot foresaw, “Between the idea and the reality . . . Falls the Shadow.” So how, this year, can we move from knowing the needed behaviors to doing them? Rocky89/iStock/Getty Images First, do make that New Year’s resolution. Research by Gary Latham, Edwin Locke, and others confirms that challenging goals motivate achievement. Specific, measurable, realistic goals—such as “finish the business plan by the month’s end”—direct attention, promote effort, motivate persistence, and stimulate creativity. Second, announce the goal to friends or family. We’re more likely to follow through after making a public commitment. Third, develop an implementation plan—an action strategy that specifies when, where, and how you will march toward achieving your goal. Research shows that people who flesh out goals with detailed plans become more focused in their work, and more likely to complete it on time. Through the ups and downs of goal-striving, we best sustain our motivation when we focus on immediate subgoals. Better to have our nose to the grindstone than our eye on the ultimate prize. Better to attend to daily study than the course grade. Better to center on small steps—the day’s running target—than to fantasize the marathon. Fourth, monitor and record progress, perhaps aided by a tracker such as a Fitbit. It’s all the better when that progress is displayed publicly rather than kept secret. Fifth, create a supportive environment. When trying to eat healthy, keep junk food out of the cupboards. Use small plates and bowls. When focusing on a project, hole up in the library. When sleeping, stash the smartphone. Choose the right friends. Such “situational self-control strategies” prevent tempting impulses, Angela Duckworth and her colleagues have found. Sixth, transform the hard-to-do behavior into a must-do habit. Habits form when we repeat behaviors in a given context—sleeping in the same comfy position, walking the same route to work, eating the same breakfast oatmeal. As our behavior becomes linked with the context, our next experience of that context evokes our habitual response. Studies find that when our willpower is depleted, as when we’re mentally fatigued, we fall back on our habits—good or bad. To increase our self-control, to connect our resolutions with positive outcomes, the key is forming “beneficial habits.” “If you would make anything a habit, do it,” said the stoic philosopher Epictetus. But how long does it take to form a beneficial habit? A University College London research team led by Phillippa Lally asked 96 university students to choose some healthy behavior, such as eating fruit with lunch or running before dinner, and to perform it daily for 84 days. The students also logged whether the behavior felt automatic (something they did without thinking and would find it hard not to do). When did the behaviors turn into habits? On average, after about 66 days. Gwyneth Paltrow recalls that when she first started working with a personal trainer, “finding motivation was hard. She advised me to think of exercise as an automatic routine, no different from brushing your teeth, to avoid getting distracted. Now it is part of my life—I exercise Monday to Friday at 10 a.m. and always stick with it.” Then do it every day for two months, or a bit longer for exercise. You likely will find yourself with a new habit, and perhaps a healthier, happier, and more productive life.  (For David Myers’ other essays on psychological science and everyday life, visit TalkPsych.com, where this essay originally appeared—here.
