Habit stacking is a strategy (adapted from BJ Fogg's tiny-habits recipe) for making a new habit obvious by linking it to a habit you already perform. The formula is: after [an existing habit], I will [the new habit] — for example, 'after I make my morning coffee, I will meditate for 60 seconds'. This removes ambiguity, which Clear argues is the real bottleneck: people think they lack motivation when they actually lack clarity about when and where the habit will occur. Once a single stack is reliable, you can chain several together into a short routine that builds momentum early in the day.
Origin
Clear credits the underlying insight to BJ Fogg, a Stanford professor whose 'tiny habits recipe' links new behaviors to existing ones. Clear packaged it as one strategy in his broader toolkit for making cues obvious.
Core principles
- 01New habits succeed more when linked to habits you already have.
- 02What people lack is usually clarity, not motivation — a specific when and where.
- 03Use the formula: after [current habit], I will [new habit].
- 04Once mastered, individual stacks can be chained into a full routine.
How to run it
- 1
Pick a reliable anchor habit
Choose a behavior you already do consistently every day, such as making a cup of coffee.
- 2
Write the stack as a formula
Phrase it explicitly: 'After I [anchor habit], I will [new habit]', giving a clear insertion point.
Pro tip The clarity of a fixed when-and-where is what removes the reliance on feeling motivated.
- 3
Keep the new behavior tiny
Start with a version small enough to take about 30 seconds so there is little resistance.
Pro tip Small stacks build momentum: six one-piece habits leave you only minutes into your day yet already moving.
- 4
Chain stacks into a routine
Once each stack is reliable, link them so the end of one habit cues the start of the next.
In the wild
Someone who already makes coffee every morning wants to meditate. They stack the habits: 'after I make my morning cup of coffee, I will meditate for 60 seconds', giving a clear, unambiguous trigger.
→ The new habit has a specific home instead of depending on vague daily motivation.
Clear chains stacks: make coffee, then meditate 60 seconds, then write the day's to-do list, then start the first item. Nothing takes more than 30 seconds each.
→ Six minutes into the day the person already has momentum and feels they are moving forward.
Common mistakes
Blaming motivation instead of clarity
Waking up hoping to feel motivated fails because the real gap is not deciding clearly when and where the habit will happen.
Starting with a behavior that's too big
Attaching a large, effortful habit to the anchor creates friction; stacks work best when each new piece is tiny.
Is it for you?
Best for
Anyone building a new daily behavior who wants a concrete, unambiguous trigger.
Not ideal for
Habits with no reliable existing anchor behavior to attach to.
From the transcript
“after I make my morning cup of coffee I will meditate for 60 seconds and so now you have this very clear place where you're…”
“often what people really lack is Clarity they don't know clearly when and where the Habit is going to occur”
