[T]he secret to a better life is not to eradicate the impulses that make us human but instead to understand them, outsmart them, and whenever possible, to make them work for us rather than against us.
Hermann estimated that forgetting follows a roughly exponential decay function. We forget nearly half of the information we’ve learned within twenty minutes. After twenty-four hours, about 70 percent of it is gone, and a month later, we’re looking at losses of approximately 80 percent.
Study after study has shown that achieving transformative behavior change is more like treating a chronic disease than curing a rash. The internal obstacles that stand in the way of change—obstacles such as temptation, forgetfulness, underconfidence, and laziness—are like the symptoms of a chronic disease. They won’t just go away once you’ve started “treating� them. They’re human nature and require constant vigilance.
Behavior change is similar. You can use an all-purpose strategy that works well on average. Set tough goals and break them down into component steps. Visualize success. Work to create habits—tiny ones, atomic ones, keystone ones—following the advice laid out in self-help bestsellers. But you’ll get further faster if you customize your strategy: isolate the weakness.
Insight: if you want to change your behavior or someone else’s, you’re at a huge advantage if you begin with a blank slate—a fresh start—and no old habits working against you.
