Most people don’t experience a crisis of happiness all at once. It’s usually much quieter, like a realization after achieving a long-sought goal that the promotion, the new apartment, or the relationship milestone didn’t bring the lasting satisfaction they expected.
Yale University psychology professor Dr. Laurie Santos has built her career around that quiet disappointment. Rather than peddling standard self-help advice on how to find happiness, Santos studies the mechanics of human delusion; specifically, how our minds systematically miscalculate what will actually make us feel fulfilled.
Her undergraduate course, “Psychology and the Good Life,” made headlines when it became the most popular class in Yale’s 300-year history, drawing in nearly a quarter of the student body. Its online adaptation, “The Science of Well-Being,” has since enrolled over 4.5 million people worldwide, complete with practical assignments, behavioral tracking, and uncomfortable self-reflection.
The demand points to a clear reality: Santos isn’t offering generic advice. She presents a functional guide to counteracting a brain evolutionarily wired for survival rather than modern contentment.
Here are the five core strategies Santos outlines to help retrain your brain for well-being.
1. Fix Your “Miswanting”
Before any of the practical steps make sense, Santos says, you have to understand why your brain has been steering you wrong. The concept she returns to again and again is “miswanting,” the deeply human tendency to want things that won’t actually make us feel better and to underestimate the things that will.
Drawing from decades of research in psychology and happiness science, Santos explains why our minds often “miswant” things we think will make us happy but won’t actually do so, and how social comparison continually moves the goalpost of our satisfaction, while practices like gratitude and social connection actually do move the needle on well-being. The salary you’ve been chasing, the house with the extra room, the number on the scale, these things register in the brain as urgent and meaningful. The research consistently shows they’re not, or at least not in proportion to the effort we spend pursuing them.
Santos challenges what she calls a common belief: “We assume that to be happier, we need to change our circumstances… but a lot of our happiness isn’t in our circumstances. It’s really in our behaviors and our mindsets.” The practical takeaway from this first step isn’t a habit, it’s an audit. Before you spend six months convinced that a different job or a bigger apartment will fix how you feel, ask whether the evidence in your own life actually supports that theory.
2. Invest in Social Connection
This is the one people most consistently undervalue. Not because they don’t believe in friendship, but because when they feel depleted, the last thing they want to do is expend energy on other people. Santos’s research suggests this instinct points directly away from what would actually help.
According to Santos, “one of the hugest effects on our own happiness is our social connection… social relationships and strong social relationships are necessary for happiness.” And the research backs this further than most people realize. It’s not just close relationships that count. A 2014 study by Sandstrom and Dunn, published in the Personality and Social Psychology Bulletin, found that even interactions with the more peripheral members of our social networks, acquaintances, neighbors, the person behind the counter, contribute meaningfully to social and emotional well-being. The researchers called this “the surprising power of weak ties.”
Santos recommends increasing social connection on a daily basis, whether that’s chatting to a stranger at the bus stop or making time to meet a friend for coffee. The coffee-shop conversation with someone you barely know, the brief exchange with the person behind the counter, these aren’t consolation prizes for people who can’t manage deeper relationships. They’re a distinct category of wellbeing support that most people are leaving on the table. If you want a concrete starting point: one genuine conversation a day, even a short one, with someone outside your household. Not a text. A conversation.
3. Practice Gratitude (Properly)
The gratitude journal has become such a fixture of wellness culture that it’s easy to treat it as a box to check rather than something that actually changes how the brain processes experience. Santos is specific about how it works, and why most people do it wrong.
Santos suggests what she calls a “delight practice,” where individuals note daily joys, training the brain to notice positive aspects of life. “If you have this practice where you got to write down the delights, your brain starts to automatically be on the lookout for them.” That last part is the point. The journal itself isn’t the intervention, it’s the trained attentional shift that happens over time.
The human brain is wired to remember more negative things than positive ones, a product of its early job keeping us alert to danger, and gratitude journaling works specifically to cement the good things in your day against that biological pull toward the negative. Santos recommends writing down three to five things you’re grateful for every night, not in a vague “I’m grateful for my family” sweep, but with enough specificity that you have to actually recall the day and find something in it. The specificity matters. A generic gratitude entry doesn’t make your brain work hard enough to locate goodness. “A stranger held the elevator” does.
4. Savor the Moment
Savoring is a concept that sounds softer than it is. It’s not about slowing down in a general sense or being more present in the abstract way that phrase gets used. It’s a deliberate, effortful act of holding a pleasant experience in attention long enough for the brain to register it fully.
Santos emphasizes that “the act of savoring is moving towards paying attention to the good things in life a little bit more.” The reason this is harder than it sounds is that modern life is specifically structured to prevent it. You buy the good coffee and drink it while answering email. You go on the walk and spend it problem-solving in your head. The pleasant thing happens and your brain, already tracking the next task, barely files it.
Savoring, the act of pausing to review and appreciate the good things or moments in life, is a key contributor to happiness. Whether you’re enjoying a moment with a friend, time in nature, or eating something delicious, the practice involves pausing and appreciating it for what it is. This is where savoring connects back to the gratitude practice. Santos describes using “counterfactual thinking,” imagining how things could easily have been worse or not happened at all, as a way to generate a quick boost of gratitude and break up “hedonic adaptation,” the brain’s tendency to normalize good things until they stop registering.
Hedonic adaptation, essentially the brain’s ability to get used to anything, good or bad, is one of the main reasons a raise or a new relationship stops feeling good relatively quickly. Savoring is one of the few tools that works against it in real time.
5. Move Your Body
The relationship between physical movement and emotional state is one of the most consistently replicated findings in all of wellbeing research. Santos isn’t telling people to train for a half marathon. The bar is much lower, and that’s actually the point.
“We often forget that bodies are connected to minds, but they really are,” Santos says. “And that means that a really quick way to change how we’re feeling emotionally is simply moving our body a little bit more.” She is clear that this isn’t about athletic performance: “Exercise is intricately connected to our mental health, and it’s important to note that this isn’t like running a marathon. This is simply just getting your body to move around a little bit more. Even as much as 20 minutes a day can really improve your well-being.”
A review published in PMC found that exercise increases the availability of brain neurotransmitters including serotonin, dopamine, and norepinephrine, the same ones that are diminished in depression, while multiple trials showed mood improvements following both acute and sustained physical activity. Movement also dials down cortisol, the body’s main stress hormone, and gives the nervous system something to do with the physical energy that anxiety and low mood tend to generate. The brain’s connection to the body is not metaphorical. Changing one genuinely changes the other, and it works faster than most people expect.
What to Do With All of This
The most important thing Santos says about happiness research isn’t any of the five steps. It’s the precondition underneath all of them: that knowing this stuff is not enough. Lasting flourishing comes through habits, small, repeated behaviors like gratitude, rest, and meaningful social time. Even small practices, ten minutes of movement, a gratitude journal entry, a real conversation, can gradually shift life toward greater happiness.
The steps above aren’t presented as revelations. Social connection, gratitude, savoring, movement, none of these sound surprising. The reason Santos’s course resonated with millions of people isn’t that she discovered something new. It’s that she gave people a framework for understanding why they keep deprioritizing the things that actually work. We know fresh air helps. We know calling a friend helps. We just consistently convince ourselves that finishing the to-do list first will help more.
The assumption that we need to change our circumstances to feel better is one of the most persistent and well-studied errors in human psychology. The behaviors are the circumstances. What you do on an ordinary Tuesday, who you talk to, what you take thirty seconds to appreciate, that is the material your brain uses to build its sense of how things are going. Santos’s contribution is making that visible enough that it becomes harder to ignore.
