# What is habit stacking?

> Habit stacking is attaching a new habit to one you already do reliably, using the formula "after I [current habit], I will [new habit]." The existing habit becomes the cue for the new one.

The term was popularized by S.J. Scott and later by James Clear in Atomic Habits. The insight is that new habits fail for lack of a reliable cue, and the most reliable cues you own are the things you already do every day without thinking: brushing your teeth, making coffee, closing your laptop.

The formula is specific on purpose. "After I pour my morning coffee, I will write down three things I need to do today." "After I take off my work shoes, I will change into gym clothes." The current habit fires automatically, and the new one rides along on that momentum.

Stacks fail when the anchor habit is not actually consistent, or when the new habit is too big for the moment. Anchor to something you truly do daily, keep the new habit under two minutes at first, and get a nudge at the exact moment the anchor happens until the link forms on its own.

## How this relates to folk

Folk turns a habit stack into a text at the right moment. Tell it "after my 7am coffee, remind me to stretch" and it nudges you at 7:05, asks whether you did it, and keeps the streak. Once the link has formed you can turn the nudge off, and folk remembers the habit either way.

## FAQ

### What are good habit stacking examples?

After I brush my teeth, I will floss one tooth. After I sit down at my desk, I will write my top task on a sticky note. After I plug in my phone at night, I will read one page. Small, specific, and anchored to something you already do every day.

### How is habit stacking different from a reminder?

A reminder is a time. A stack is a behavior. "8am: stretch" fires whether or not you are ready; "after coffee: stretch" fires when you are already in the routine. A reminder timed to the anchor habit is the bridge until the stack runs on its own.
