​Dr. B. J. Fogg, author of Tiny Habits: The Small Changes that Change Everything presented his formula for adopting new habits in The Wall Street Journal. He said his formula applies to everything from flossing your teeth to running marathons. In his words, “To instill a habit, the first thing you need is motivation; Pick a behavior that you want to do rather than one you merely feel obligated to do. Second, you need to be able to do it: Make the change simple and small at first. Third, you need a personal prompt: Identify a way to trigger the behavior. Finally, you need to celebrate your new habit so that your brain associates it with positive feelings. I used this same process when I wanted to make flossing my teeth a daily habit. So, every morning when I finished brushing my teeth, that was the trigger to floss. When I finished flossing, I celebrated with a fist pump in front of the mirror. That was 40 years ago, and I haven’t missed a day since. I’m now using this same process to make sure I walk every day.
