During the Enactus and OCP Foundation program in Laayoune, the plan was simple: stack a new habit, reviewing the previous day’s dashboard numbers, onto an existing one, checking email. The idea came straight from the popular habit-stacking framework: attach the new behavior to something already automatic, and it should stick without much effort.
It didn’t stick. Not because reviewing dashboard numbers was hard, and not because the framework was wrong. It failed because checking email wasn’t actually the fixed, automatic anchor it felt like. Some mornings it happened from a phone before arriving at the office. Other mornings it happened after a first conversation with a colleague. The anchor moved around just enough that the new habit never had a stable place to attach to.
Habit stacking usually fails for a reason almost nobody checks first: the anchor habit itself has to be genuinely fixed, happening the same way with zero exceptions, not just something that happens “usually.” A new habit stacked onto an inconsistent anchor inherits that inconsistency. The framework gets blamed for not working, when the actual problem was choosing an anchor that only felt reliable.
Key Takeaways
- Habit stacking usually fails because the anchor habit wasn’t actually fixed, it just felt reliable most of the time.
- A new habit stacked onto an inconsistent anchor inherits that anchor’s inconsistency.
- The habit that finally held was attached to something with zero exceptions: turning on the office computer every single working day.
- Test an anchor honestly for a week before stacking anything onto it: does it happen the same way every day, with no exceptions.
- If the honest answer about an anchor is “mostly,” it isn’t a stable anchor yet.
What changed once the anchor was fixed
The habit stuck once it got re-attached to something with no exceptions at all: turning on the office computer each morning. That single physical action happened literally every working day, in the same order, regardless of what else had already happened that morning. The dashboard review moved right after it, and it held, not because the new habit had gotten easier, but because the anchor finally deserved the weight being put on it.
Before stacking anything new onto an existing habit, it’s worth testing the anchor honestly for a week: does it happen the same way, every single day, with zero exceptions. If the answer is “mostly,” that’s not a stable anchor yet.
FAQ
What makes a good anchor habit?
Something so fixed it barely qualifies as a decision: turning on a specific device, sitting at a specific desk, a first physical action that happens the same way regardless of mood or schedule. The more automatic and exception-free it already is, the better it works as an anchor.
What if no habit in the day is that consistent?
That’s worth noticing on its own. A day with no genuinely fixed anchor points usually means the day itself is less structured than it feels, which is a bigger issue than any single new habit.
How long should you test an anchor before trusting it?
About a week of honest observation is usually enough to see whether it holds without exception. If it survives a full week including the unpredictable days, it’s a reasonable anchor to build on.
