made sense to place a high value on instant gratification. The distant future was less of a concern. And after thousands of generations in an immediate-return environment, our brains evolved to prefer quick payoffs to long-term ones.
Behavioral economists refer to this tendency as time inconsistency. That is, the way your brain evaluates rewards is inconsistent across time.* You value the present more than the future. Usually, this tendency serves us well. A reward that is certain right now is typically worth more than one that is merely possible in the future. But occasionally, our bias toward instant gratification causes problems.
Why would someone smoke if they know it increases the risk of lung cancer? Why would someone overeat when they know it increases their risk of obesity? Why would someone have unsafe sex if they know it can result in sexually transmitted disease? Once you understand how the brain prioritizes rewards, the answers become clear: the consequences of bad habits are delayed while the rewards are immediate. Smoking might kill you in ten years, but it reduces stress and eases your nicotine cravings now. Overeating is harmful in the long run but appetizing in the moment. Sex—safe or not—provides pleasure right away. Disease and infection won’t show up for days or weeks, even years.
Every habit produces multiple outcomes across time. Unfortunately, these outcomes are often misaligned. With our bad habits, the immediate outcome usually feels good, but the ultimate outcome feels bad. With good habits, it is the reverse: the immediate outcome is unenjoyable, but the ultimate outcome feels good. The French economist Frédéric Bastiat explained the problem clearly when he wrote, “It almost always happens that when the immediate consequence is favorable, the later consequences are disastrous, and vice versa. . . . Often, the sweeter the first fruit of a habit, the more bitter are its later fruits.”
Put another way, the costs of your good habits are in the present. The costs of your bad habits are in the future.
The brain’s tendency to prioritize the present moment means you can’t rely on good intentions. When you make a plan—to lose weight, write a book, or learn a language—you are actually making plans for your future self. And when you envision what you want your life to be like, it is easy to see the value in taking actions with long-term benefits. We all want better lives for our future selves. However, when the moment of decision arrives, instant gratification usually wins. You are no longer making a choice for Future You, who dreams of being fitter or wealthier or happier. You are choosing for Present You, who wants to be full, pampered, and entertained. As a general rule, the more immediate pleasure you get from an action, the more strongly you should question whether it aligns with your long-term goals.*
With a fuller understanding of what causes our brain to repeat some behaviors and avoid others, let’s update the Cardinal Rule of Behavior Change: What is immediately rewarded is repeated. What is immediately punished is avoided.
Our preference for instant gratification reveals an important truth about success: because of how we are wired, most people will spend all day chasing quick hits of satisfaction. The road less traveled is the road of delayed gratification. If you’re willing to wait for the rewards, you’ll face less competition and often get a bigger payoff. As the saying goes, the last mile is always the least crowded.
This is precisely what research has shown. People who are better at delaying gratification have higher SAT scores, lower levels of substance abuse, lower likelihood of obesity, better responses to stress, and superior social skills. We’ve all seen this play out in our own lives. If you delay watching television and get your homework done, you’ll generally learn more and get better grades. If you don’t buy desserts and chips at the store, you’ll often eat healthier food when you get home. At some point, success in nearly every field requires you to ignore an immediate reward in favor of a delayed reward.
Here’s the problem: most people know that delaying gratification is the wise approach. They want the benefits of good habits: to be healthy, productive, at peace. But these outcomes are seldom top-of-mind at the decisive moment. Thankfully, it’s possible to train yourself to delay gratification—but you need to work with the grain of human nature, not against it. The best way to do this is to add a little bit of immediate pleasure to the habits
