Choosing a cue
Time, place, a preceding event or a person — and which kind fits your life.

The problem it solves
What should actually start your habit?
The concept
A good cue happens every day (or every time the habit is due), is easy to notice, and comes at a moment when you can actually act. There are four common kinds: a time (“at 7am”), a location (“when I sit at my desk”), a preceding event (“after I pour my coffee”), and a person (“when my running partner messages”).
Preceding-event cues are often the strongest because they’re already built into your day and happen at a natural break. Time cues work well if your schedule is steady; location cues work when you’re reliably in a place.
The best cue is the one that fits your real life. If your mornings vary, “after I brush my teeth” beats “at 7am”.
Why it matters
Implementation-intention research shows that linking a behaviour to a specific situation helps people act on intentions. A randomised trial found routine-based and time-based cues worked similarly — so pick the one that is most reliable in your days.
Research-supported: Good studies support it, but there are fewer of them, the effects are modest, or they come from a narrow set of situations.
See it happen
Elif plans to meditate “sometime in the evening”.
- The ordinary first approach
- The evening is flexible, which should make it easier to fit in.
- With the idea
- She picks a preceding event that always happens: right after she washes her face at night, on the same cushion.
- What changed
- A vague window became a specific moment that shows up every night.
Easy to get wrong
- Using “when I have time” — that isn’t a cue.
- Picking a cue that only happens some days.
- Choosing a moment when you can’t actually do the habit, like “when I get to work” for a home activity.
Try it now: List your daily anchors
- Write five things you do every day without fail — wake up, make a drink, brush teeth, sit down to work, get into bed.
- Next to each, write a habit that could fit right after it.
- Pick the pairing that feels most natural.
Apply it to one of your habits
For one of your habits, choose one cue — time, place, preceding event or person — and write it down.
Reflect
- Which kind of cue fits your life best — time, place, event or person?

Techniques that use this idea
- Make an action plan — Decide when, where and how you’ll do it — before the moment arrives. (Supported by multiple studies)
Problems this helps with
- “I keep forgetting.” — You mean to do it, and then the moment slips past — you remember at night, or not at all.
