Somewhere in the middle of building my startup, I forgot there was an end goal.
Not in the way people talk about losing their north star or drifting from their mission. I mean something simpler and more embarrassing than that. I forgot that a finished thing could exist. That you could start something, work through it, and arrive at a point where it was done. That "done" was even a real category available to me.
The startup had no such category. There was always another problem, another hire, another decision, another fire. The work did not accumulate toward a finish line. It just continued. And after enough time of that, something in me stopped looking for one.
That is when I picked up Lego again.
01The thing about the last brick
I do not remember what made me buy the first set as an adult. I think it was impulse, nostalgia, a Saturday with nowhere to be. What I did not expect was how it would feel when I placed the last piece.
It sounds like a small thing. It is a small thing. But finishing a Lego model produces a sensation that is almost pharmacological. There is a specific exhale that happens. A release. Your brain registers that something is closed, and it responds accordingly.
There is actual science behind why this feels the way it does. Psychologist Bluma Zeigarnik documented in 1927 that unfinished tasks occupy mental space in a way finished ones do not. The brain keeps an open file on incomplete goals and only closes it when the task is done. Masicampo and Baumeister confirmed this in 2011, finding that unfinished goals create measurable cognitive interference, occupying working memory, pulling attention away from other things, surfacing as intrusive thoughts. Simply completing a task closes the file. The relief is real and it is neurological.
A startup is, by design, a permanently open file. It does not close. Every week you add more open loops than you resolve. Over months and years, the cumulative weight of that becomes something you carry without realizing it. You stop expecting relief because relief stopped showing up.
The Lego set has a last brick. And when you place it, your brain finally gets to close something.
02Why it has to be with your hands
I am not suggesting you need Lego specifically. But I do think it has to be something physical, something you make with your hands, and something with a visible end state.
Neuroscientist Kelly Lambert has spent years studying what she calls the effort-driven rewards circuit, the neural pathway activated when your hands produce something you can see and touch. Her finding is counterintuitive: this circuit, not intellectual achievement or abstract success, is what most reliably lifts mood and restores a sense of agency. The hands are disproportionately represented in the brain's motor and sensory cortex. Moving them toward a tangible result activates something that emails and strategy decks simply cannot reach.
Lego, specifically, is almost engineered for this. It has clear instructions, which creates clear goals. Every piece clicks into place, which is immediate feedback. The challenge scales with what you buy. Psychologist Mihaly Csikszentmihalyi spent decades studying the mental state that produces the deepest satisfaction and described it as flow: complete absorption in an activity with clear objectives, instant feedback, and a matched challenge-to-skill ratio. A well-chosen Lego set checks every box.
LEGO commissioned a study in 2022 of 33,429 adults across 33 countries. Ninety-three percent reported feeling regularly stressed. Eighty-six percent said play helped them unwind. Fifty-five percent said they had a hard time switching off from work. These are not niche numbers. This is just the baseline condition of being an adult with responsibilities, compounded for founders who have taken on a specific kind of relentless mental load.
David Beckham, who has been public about his OCD, has described building Lego at two in the morning because he needed to finish a piece. When someone asked how he felt completing the Hogwarts castle, he said: "Accomplished." That word does real work. Not proud. Not happy. Accomplished. The sensation of having done something with a beginning and an end.
03The founder trap
There is a myth in startup culture that the best founders never stop, never rest, never look back. That the company is always a work in progress and treating it as anything else is complacency. I understand where this comes from. Startups are hard and competitive and you can always be doing more. But I think this framing quietly damages people in a way that compounds over time.
A study published in the journal Small Business Economics found that 49% of entrepreneurs in their sample had a lifetime history of a mental health condition, significantly higher than the general population. A more recent survey of European founders found 54% had experienced burnout in the past year, with 49% saying they had considered quitting their startup entirely. These are not edge cases. This is what sustained open-loop living does to people.
Brad Feld, one of the most respected voices in venture, has spoken openly about the depressive episodes he experienced while building companies. He has said that tying your happiness to milestones is a trap because the milestones never stop arriving and the gaps between them expand to fill whatever space you give them.
The "never done" story is also just factually wrong about how great companies work. The greatest startups do not succeed by never finishing anything. They evolve. They ship, they learn, they change direction. Evolution is not the same as never arriving. You can move forward and also look back at what you have built. These are not opposing activities. They are both necessary.
04Multiple finish lines
I used to think that finishing something meant stopping. That celebrating a milestone meant taking your foot off the gas. I do not think that anymore.
Teresa Amabile and Steven Kramer spent years analyzing diary entries from hundreds of employees and found that the single most important factor in positive inner work life was making progress in meaningful work. Not finishing everything. Not solving every problem. Progress. And specifically, the experience of small wins, of completing contained things, of seeing that movement was happening.
Their research showed that even minor progress events produced outsized positive emotional responses. The brain is not waiting for the big exit. It runs on evidence of forward motion.
You do not need to stop building the startup to complete a goal. You can have multiple finish lines. The quarterly milestone is one. The product launch is one. The Lego set is one. They do not compete with each other. The dopamine from finishing the model does not deplete your ambition for the company. If anything, the research on multiple-goal pursuit suggests the opposite: completing one goal replenishes the energy you bring to others.
This is why I build Lego every couple of months and not every day. It is a scheduled reminder that finished things exist. That I am capable of starting something and seeing it through to the end. That the sensation I almost never get from the company is still available to me, in a more contained form, on a Saturday afternoon.
05Be kind to yourself
This is the part that took me the longest to accept.
The founder identity has a lot of mythology built around toughness. Around not needing validation, not needing rest, not needing to hear that you did something well. The culture rewards people who appear to operate without these things. And so founders perform not needing them, even when they do, even when the deprivation is accumulating in ways they cannot fully see.
Kristin Neff has spent over two decades studying self-compassion and found something that runs directly against the way startup culture talks about motivation. Self-criticism, she found, activates the threat-defense system. It produces fear, shame, and a freeze response. It is not a reliable engine for sustained performance. Self-compassion, by contrast, is associated with higher grit, greater willingness to take risks, faster recovery from failure, and stronger intrinsic motivation. People who treat themselves with basic kindness aim just as high as those who do not. They just survive the process better.
A randomized controlled experiment with active entrepreneurs found that brief practices that built self-compassion reduced fear of failure when facing venture obstacles. This is not soft advice. It is a performance argument backed by evidence.
Looking back at what you have built and acknowledging that it is real, that your effort meant something, that you moved the needle even when it did not feel like it — this is not weakness. It is calibration. It is the cognitive act of closing a file that has been open long enough.
Your effort is not wasted. That sentence sounds simple. For a lot of founders I know, it lands like something they have not heard in years.
06What I actually do
I build a Lego model every couple of months. Usually when I have a break, sometimes when I need one. I do not rush it. I follow the instructions. I place the last piece, and I sit with it for a minute.
It reminds me that I am capable of finishing something. That finished things exist. That the version of me who started this company had an end goal in mind, and that goal is still there, even when the daily work makes it invisible.
The startup will keep going. That is fine. It is supposed to. But I am not only the startup. I am also the person who builds things, who finishes what he starts, who is allowed to look back at what he has built and acknowledge that it happened.
Start something small. Build it to the last piece. Sit with what that feels like. Then get back to work.
