A revisit of an old post on happiness — what I had right, what I had wrong, and what thirteen years of research has changed in how I understand joy.

In 2013, I wrote a blog post called Optimize Brain Function and Create Happiness. It was a list of twenty-five things — meditation, journaling, gratitude, exercise, kindness, supplements with specific dosages, positive thinking, eye contact, power posing, and so on. The post did well at the time. It captured what was current in the cultural conversation about happiness then. And reading it now, more than a decade later, I see that some of what I wrote has held up beautifully and some of it has not.

This post is a revisit. Not a replacement of the original — that one is still there if you want to look at it. A genuine rethinking of what I have come to understand about happiness in the years since I wrote it. The work I do as a Licensed Marriage and Family Therapist has changed me. So has the field. Some things that seemed straightforward in 2013 are more complicated than I knew. Some things I did not yet understand have become central to how I think about wellbeing.

Here is what has changed.

What I had right

Small changes still matter. That was the heart of the 2013 post and it remains true. Daily practices, repeated over time, produce more change than dramatic interventions. The brain and the body respond to consistency more than to intensity. A short daily meditation done for months produces results that a long retreat experience does not match. A gratitude practice of three things, written down most evenings, accumulates into a different relationship with one’s life over a year.

The basics still matter. Movement, sleep, hydration, time in nature, reduced exposure to chronic stress, regular meals — these are not glamorous interventions. They are the conditions under which the nervous system can function. Without them, no amount of mindset work will reach the underlying physiology that determines so much of what we call happiness.

Other people matter. The 2013 version of the post emphasized surrounding yourself with positive people, and that observation has been deepened rather than overturned by subsequent research. The single most consistent finding in happiness science over the past two decades is that the quality of your close relationships predicts your well-being more reliably than almost any other factor. Not the number of relationships. Not their visible success. The felt quality of being loved, seen, and known by the people closest to you.

What I had wrong

I framed happiness as a choice, full stop. “Happiness is a choice,” the original post said. It is not entirely wrong, but it is not entirely right either. Happiness involves choices, certainly — daily practices, attention to what fills you, willingness to engage in relationships that nourish you. And it is also significantly shaped by genetic factors, by current life circumstances, by physiological conditions that no amount of choosing can override, by trauma history, and by the social and economic conditions in which a person is trying to live.

Telling someone who is depressed that happiness is a choice often produces shame rather than help. The choice framing works for people whose baseline state is already pretty stable and who can benefit from small adjustments. For people whose baseline state has been compromised by depression, anxiety, chronic stress, unprocessed trauma, or serious medical conditions, the choice framing can be actively harmful. It implies that their suffering is, in some way, their own fault. It is not.

I included specific supplement dosages. I would not do that today. Blog posts are not the right place for supplement recommendations, both because the research has shifted on most of what I listed and because the legal and ethical standards around supplement advice have tightened appropriately. Anyone considering supplements should talk to their doctor or to a licensed nutritionist who can assess them as individuals rather than reading dosing recommendations from a blog post.

I listed twenty-five things. That was the format of 2013 blog writing, and lists still have their uses. But for a topic as layered as happiness, the list format can flatten what is actually a deeply nuanced subject. The list suggests that happiness is the sum of these twenty-five practices done consistently. It is not. Happiness is more relational, more physiological, more contextual, and sometimes simpler than a list of practices can capture.

What the field has learned since 2013

Sonja Lyubomirsky, who is one of the most influential happiness researchers working today and a Distinguished Professor at UC Riverside, has spent the past decade refining what she calls the architecture of sustainable happiness. Her work shows that happiness interventions do produce real change when sustained over time — but the change is more durable when the interventions are matched to the person doing them. Gratitude practices work better for some people than for others. Acts of kindness produce more benefit when they are varied rather than routinized. The how matters as much as the what.

Most recently, Lyubomirsky has published a book called How to Feel Loved, co-authored with Harry Reis of the University of Rochester. The book, released in early 2026, makes a striking argument grounded in decades of research. The single most reliable difference between happy and unhappy people is not money, success, or even health. It is whether they feel loved — felt loved, in their bodies, in ordinary moments, by the people closest to them. “To feel that the people in your life truly get you, value you, and love you,” Lyubomirsky and Reis write, “is what makes life worth living.”

This finding has changed how I think about happiness. It also resonates with the trauma and attachment work I do daily in my practice. The people who struggle most with happiness are very often people who, for reasons rooted in their earliest relationships, do not feel loved at a felt-sense level — regardless of how much love is actually present in their current lives. Their nervous systems were calibrated by early conditions to filter out the love that is being offered. The work of becoming happier, for these clients, is not a matter of adopting more positive practices. It is the work of slowly developing the capacity to feel love when it arrives.

Barbara Fredrickson, at the University of North Carolina, has shown through decades of research that positive emotions, even brief ones, produce measurable changes in cognition, social behavior, health, and resilience. Her broaden-and-build theory describes how moments of positive affect open the mind and build durable resources over time. More recent work from her Positive Emotions and Psychophysiology Lab has focused on what she calls positivity resonance — the felt sense of shared positive emotion between two people in conversation, in eye contact, in the simple moments of being together. These small shared moments are not decorative. They are the building blocks of the longer-term well-being that all the other practices try to produce.

What I would tell my 2013 self

Keep the small practices. They matter. Add to them the recognition that happiness is not primarily a matter of individual optimization but of relationship — to your own body, to the people in your life, to whatever you understand as larger than yourself.

Stop treating happiness as a target. Treat it as a byproduct of a life lived in close connection to the things and people that genuinely matter to you. The targeting itself, paradoxically, often gets in the way. People who aim directly at happiness frequently miss it. People who orient their lives toward meaningful work, close relationships, and genuine presence often find happiness arriving, more or less on its own, in the spaces those orientations create.

Be honest about what is not yours to fix. The chronic depression rooted in unprocessed trauma. The anxiety that has somatic components requiring medical care. The deep loneliness that small practices alone cannot reach. These conditions deserve respect, not optimization advice. The right response is often professional support — therapy, medical care, sometimes medication — rather than another daily practice.

And know that the small practices are still worth doing. The gratitude. The breath. The walk in the morning. The person you love. The work that means something to you. The thirteen years that have passed since the original post have only confirmed how much the small things matter — and how much they need to be set within the larger context of relationships, conditions, and the genuine work of becoming oneself.

Where to begin today

If you are reading this and looking for one practice to begin, here is what I would suggest. Once today, pause and notice one small thing you genuinely appreciate about someone in your life.

Not a polite thought. An actual felt sense of appreciation. Then, sometime today, tell them.

Briefly. Specifically. Without needing them to respond in any particular way.

This single practice, repeated regularly over months, produces more measurable change in wellbeing than almost any other single intervention I know. It builds the very thing that

Lyubomirsky and Reis identify as central — the felt sense of being loved, which arrives when we extend love in ways the other person can receive. Each act of specific appreciation is a small revision of the relational climate of your life. The climate, over time, is what we call happiness.

That is what I have come to understand. Happiness is not a mood. It is a relationship. With yourself. With others. With the conditions of your life. The work of building it is real, and the work is slower and more relational than the lists suggested. And it is genuinely worth doing.
