Self-Determination Theory Examples: 5 From Everyday Life

You loved it once. The drawing, the side project, the sport you played for no reason but that you wanted to. Then something shifted, and now it sits there like an obligation — a thing you should get back to. Nothing dramatic happened. The activity is identical. But the wanting has drained out of it.

Self-determination theory is the psychology that explains why, and the clearest way to grasp it is not a definition — it is watching it operate. In short: people stay motivated when three needs are met — autonomy, competence, and relatedness — and when one of those is starved, motivation collapses no matter how good the goal looks. (For the mechanism itself — the three needs, the research, why forcing it backfires — the place to start is why willpower fails.) What follows is the theory in five ordinary lives, with the starved need named in each.

The thing you used to love that now feels like a chore

Start with the drawing. You did it for years because you enjoyed it — that was the whole reason, and the whole reason was enough. Then you started selling commissions. Within a few months you noticed you didn’t want to draw at all, even on your own time.

What happened has a name: the overjustification effect. An external reward — money, in this case — overwrote the internal reason. You used to draw because you chose to; now you draw because a client is waiting. The activity that fed your sense of acting from your own reasons now serves someone else’s deadline. The need that got starved is autonomy — not freedom in the vague sense, but the specific feeling that what you’re doing is yours.

The reward didn’t add to the reason. It replaced it.

This is the example that catches people off guard, because it runs against intuition. We assume paying someone to do what they already love would make them love it more. Reliably, it does the opposite.

When the promotion killed the part you liked

A developer spends years happily building things. She is good at it, she can see herself getting better, and the work absorbs her. Then she gets promoted to manager — more money, better title, the obvious next step. And the motivation she never had to think about starts to evaporate.

The part she actually liked — solving problems with her own hands, watching something work that didn’t work an hour ago — is gone, replaced by meetings about other people’s work. Two needs went at once. Competence: she no longer feels the daily progress at a craft she’s good at; managing well is real, but she can’t see herself improving at it the way she could see a feature ship. And autonomy: her day is now shaped by everyone else’s problems. The reward (the promotion) was real, but it cost her the two needs the old job quietly met.

Going back to school — the returning adult student

A man in his forties enrols in a course after twenty years away from study. For the first weeks he forces every session and retains almost nothing. Then one assignment asks him to apply the material to his own work — and suddenly he’s reading ahead, unprompted.

The shift wasn’t discipline. It was relatedness and autonomy arriving together. The moment the material connected to his actual life — his job, his family, the reason he came back — it stopped being abstract homework imposed from outside and became something he was learning for his own reasons. Returning students reliably describe this exact turn: motivation didn’t precede the relevance; it followed it. The need was there waiting to be met, and the right framing met it.

Why the reward chart stopped working

A parent puts up a sticker chart to get a child to read. It works for two weeks. Then the child reads only when a sticker is on offer, complains when the chart is full, and stops reading the moment the rewards end.

This is the overjustification effect again, in its most common domestic form. The child read for the sticker, not the book — the external reward replaced the internal reason rather than adding to it. The famous demonstration came from the psychologist Edward Deci in 1971: people paid to do an interesting puzzle stopped doing it once the pay stopped, while an unpaid group kept going for the fun of it. The reward, it turned out, didn’t stack on top of the interest. It overwrote it. The starved need is autonomy — the child’s sense that reading was something they did, not something they were paid to perform.

At the gym — why some people stick and some quit

Two people start exercising in January. One is gone by February; the other is still going a year later. The difference usually isn’t willpower, and it usually isn’t the workout.

The one who sticks has, somewhere, found a need being met. Often it’s competence — they picked something where they can see themselves improving (lifting more, running further, a skill that visibly sharpens), and the felt progress is its own fuel. Sometimes it’s relatedness — a class, a training partner, a community where showing up means something to other people. The one who quits is usually grinding at something that meets no need: an activity they don’t enjoy, can’t see progress in, and do alone, sustained by nothing but the intention to be the kind of person who exercises. That intention is willpower, and willpower is exactly the finite resource that runs out.

How to tell which need is starving in your own example

You don’t need the framework to use the pattern. When motivation for something has quietly died, ask which of three things is missing — and the examples above are the diagnostic, not a checklist to memorise.

Is the thing no longer yours — has it become something you do for a reward, a deadline, or someone else’s expectation? That’s autonomy, like the drawing and the sticker chart. Can you no longer see yourself getting better at it — has progress flattened or become invisible? That’s competence, like the promoted developer and the gym quitter. Or does it no longer connect you to anyone — are you doing it alone, for reasons that touch no one you care about? That’s relatedness, like the student before the material became relevant.

The point of naming it is that need deficits have different fixes than character flaws do. You cannot discipline your way out of a starved need. You can only feed it — restore the choice, rebuild the visible progress, reconnect it to people — and watch the motivation you were trying to force return on its own.

The older idea this keeps confirming

It is worth noticing how old this is. Edward Deci and Richard Ryan built self-determination theory from the 1970s onward by doing something the thinkers before them couldn’t: they measured it, in controlled experiments. But what they measured was not new.

You can read their three needs as the empirically tested version of what Abraham Maslow gestured at when he put self-actualization — becoming everything you are capable of becoming at the top of his hierarchy: the conditions under which a person becomes genuinely self-directed rather than driven. And further back still, Aristotle argued that a good life is one of activity freely chosen and done well — virtue as something you do from your own settled character, not because you are made to. Deci and Ryan put instruments on a claim roughly twenty-three centuries old: that a person flourishes when their actions are their own, when they are good at something that matters, and when they are bound to others. The lab confirmed the philosophy. The needs were always there. We just finally found a way to watch them starve.
