Building this blog has given me a fairly personal interest in the question of what makes people keep going. There's the enjoyable part, when I find something strange and can't wait to write about it, and then there's revising the article, checking a source, fixing an older post and trying to work out what the analytics are actually telling me. Curiosity starts a lot of projects. Getting them into a shape somebody else can use involves considerably more returning to the same desk.
I care about building something that can support my future and my family. That makes persistence feel meaningful to me, although I also know how easily a meaningful goal can acquire an enormous to-do list and start behaving like an additional landlord. Apparently, even a dream can get demanding about what you owe it by Friday.
We often call the ability to stay with a long project grit. The word has a satisfying sound, as though it ought to come with sturdy boots and an unusually reliable alarm clock. I wanted to know what researchers mean by it, what the brain research actually shows and how much of the popular advice survives a closer look.
What Researchers Mean by Grit
Angela Duckworth and colleagues defined grit as perseverance and passion for long-term goals in their 2007 research paper. They studied outcomes including educational attainment, grades, military training retention and spelling-bee performance. Grit predicted a portion of the differences in those outcomes, with the paper reporting an average of about 4% of the variance explained across its studies.
That percentage describes a statistical relationship in those samples. It doesn't mean grit is responsible for 4% of any particular person's life, or that the rest can be divided neatly among talent, money and luck. The research gave psychologists a way to investigate sustained commitment, while leaving plenty of room for other explanations of why people succeed.
A 2019 study following 11,258 West Point cadets adds an interesting distinction. Grit was useful for predicting completion of initial training, while cognitive ability was the strongest measured predictor of academic and military grades. Different attributes helped predict different outcomes. Finishing a demanding training period and earning a high grade were related questions, but they weren't interchangeable ones.
The Research Also Gives Grit a Reality Check
A 2017 meta-analysis of 88 independent samples involving 66,807 people found that grit overlapped strongly with conscientiousness, a broader personality trait involving tendencies such as dependability and organization. The perseverance component was more useful for predicting outcomes than consistency of interests. The authors questioned how much a separate grit concept added and cautioned about expecting large gains from interventions aimed at increasing it.
I find that distinction between effort and unchanging interests particularly useful. A person can keep working toward something important while learning that their first plan needs improvement. If staying interested in the identical thing forever were the main requirement, my collection of interests would probably disqualify me before breakfast.
The studies also don't give us a character-ranking system. A questionnaire about persistence can't tell us whether two people have comparable time, health, money, support or responsibilities. Before deciding that somebody else gave up too easily, I'd want to know considerably more about what continuing would have required from them.
Dopamine Makes This Interesting, and Complicated
Dopamine is involved in learning and motivation, which makes it relevant to questions about effort. A 2019 study in rats examined dopamine-cell activity and dopamine release during a reward-based decision task. It found differences in the signals associated with learning about rewards and the signals related to changing reward expectations and motivation.
The important detail is how specific that experiment was. It studied particular signals in a particular task, rather than comparing people who finished novels with people who abandoned them. A chemical involved in motivation gives us a starting point for understanding behavior, and researchers still have to establish which findings explain sustained effort toward a complicated goal.
That is a considerably more interesting picture than giving dopamine a single job title. It also leaves me cautious about claims that every difficult task automatically earns a little chemical reward for trying, or that people with grit have one unusually strong brain pathway. Those would need their own evidence, rather than borrowing credibility from the fact that dopamine has something to do with motivation.
Two Patients and a Very Unusual Experiment
One of the stranger studies in this area involved electrical stimulation of the anterior midcingulate cortex in two patients undergoing invasive monitoring for epilepsy. In the 2013 study, stimulation produced bodily changes and a sense of an approaching challenge accompanied by determination to overcome it. Researchers also examined connections between the stimulation sites and a wider brain network.
I can see why a finding like that attracts attention. A subjective feeling of determination is difficult to pin down, and here scientists could investigate a change in that experience during direct stimulation. But two patients reporting a state during a clinical procedure is a very different kind of evidence from showing how a personality trait develops over decades.
The study offers a clue about a network involved in a determined response. It doesn't give us a scan that identifies who will finish a degree or a prescription for growing a particular brain region by doing chores we dislike. The gap between an intriguing experiment and a universal life rule is often where the most enthusiastic advice gets ahead of itself.
Starting Points Differ, and They Can Still Change
A 2016 study of 4,642 British teenagers from twin pairs found both genetic and environmental contributions to differences in grit scores. It also found that grit added little to predictions of exam results beyond established personality measures, particularly conscientiousness. That complicates the idea that grit is entirely learned through deciding to try harder.
Heritability describes variation in a studied population under particular conditions. It doesn't tell an individual what percentage of their persistence is fixed, and it doesn't establish a ceiling on what they can learn. I think there's room to acknowledge different starting points while still being curious about which habits, resources and forms of support make continuing more manageable.
Practice Works Better When It Gives You Information
Returning to a task can create opportunities to improve, especially when the practice targets something specific. In a study of National Spelling Bee competitors published in 2011, grittier participants did more deliberate practice, which helped statistically explain their performance. The focused practice was also rated as less enjoyable than other preparation activities.
That was evidence from spelling competitors, rather than a demonstration that every unpleasant activity builds a useful skill. What interests me is the connection between effort and information. Working on a spelling weakness gives a learner something more specific to change than a general instruction to become an impressive person.
I can apply that distinction to writing without turning my laptop into a psychology laboratory. Revising a confusing explanation, checking whether a source supports a sentence or figuring out why an introduction wanders gives the work a direction. Repeating the same problem with greater determination would certainly keep me busy, but I'd rather the next version actually improve.
A Useful Mindset Needs Somewhere to Work
Growth mindset is often bundled together with grit, although the concepts are different. A large 2019 experiment in American high schools tested a short intervention teaching that intellectual abilities can develop. It improved grades among lower-achieving students, and the study found that school context, including peer norms supporting challenge-seeking, mattered for sustaining the effects.
I like that the environment has a place in this result. Encouraging somebody to improve makes more sense when they also have opportunities to practice, get useful feedback and ask questions. The study concerned a specific educational intervention, so it shouldn't become a promise that a different attitude will solve every obstacle in a person's life.
The gardening comparison is almost too easy here, but I'm going to use it anyway. I can want a seedling to grow with considerable enthusiasm, while the actual plant remains interested in water, light and the condition of its roots. The goal can matter deeply, and the conditions can matter at the same time.
A Routine Can Make Returning Less of a Production
Habit research gives us another useful piece. In a real-world study published in 2010, participants repeated a chosen eating, drinking or activity behavior in a consistent context and reported how automatic it felt over time. Automaticity generally developed gradually, with substantial differences between people and behaviors. Missing a single opportunity didn't materially disrupt the process in that study.
Simple daily behaviors are a different task from sustaining an entire business, but I find the gradual part reassuring. A familiar starting point can save a person from having to invent the whole beginning again. For writing, “check the source for this paragraph” is a much more approachable place to start than “build your entire future before lunch.”
I'm also happy to leave room for returning after an interruption. A plan that has somewhere to resume seems more useful to me than one that collapses the moment a day goes sideways. Life has a remarkable talent for arriving with additional requirements just when the calendar starts looking organized.
Changing a Goal Can Be Part of Taking It Seriously
There is research on letting go, too. In three studies published in 2003, researchers examined how people disengaged from unattainable goals and engaged with alternatives. Those abilities were associated with aspects of subjective well-being. The work doesn't tell us which particular project someone should leave, but it gives goal adjustment a legitimate place in the conversation.
I think that matters for anybody trying to build something over a long period. New information might change the timeline, the method or the goal itself. Continuing to care about your future can include deciding that a particular route is taking more from your life than it can reasonably give back.
Rest belongs in my understanding of commitment as well. I want a project that can become part of a life I enjoy, and the life has to be allowed to exist while I'm working on the project. Sleep, relationships and ordinary time away from a task deserve room in the plan, rather than waiting somewhere beyond an endlessly moving finish line.
What Building This Blog Has Made Me Think About
I've written before about the drive to keep building after difficult experiences, and that connection still matters to me. Working toward a future can feel hopeful and concrete when other things have felt uncertain. I also want to be able to appreciate the work without making constant productivity the evidence that I'm doing well.
The blog involves a lot of returning. Returning to a draft, an old explanation, a source or an idea that needs a better way into the story. There is satisfaction in that, even when the task in front of me is considerably less glamorous than announcing a brand-new project.
I still want this work to help create more freedom for my future and my family. The question I find useful is whether the effort is helping build that life, and what I can learn from the results. A higher post count alone can't answer it, which is slightly inconvenient for the part of me that would enjoy a very clear scoreboard.
I've also previously mentioned NeoRhythm in connection with focus. That earlier personal experience sits separately from evidence about grit. The manufacturer describes it as a general wellness device, and my experience doesn't establish that it rewires perseverance, treats a condition or improves somebody else's results.
I came into this subject interested in the people who keep going, and I still am. Now I'm equally interested in what makes returning possible: a meaningful goal, a useful next step, feedback, support and enough room to reconsider the plan. I find that version considerably easier to live with than the idea that every pause needs defending.
I'll probably remain a little stubborn about the things I care about. I'd just like that stubbornness to have a conversation with the evidence occassionally, including the evidence from my own life about what the work is costing and what it's giving back. There's plenty worth continuing toward, and I'd like to arrive with enough of a life left to enjoy it.
