The most effective cues are ones anchored in time and/or space.

  • Habit Score Cards track progress and gamify consistency.
  • Stacking uses a current habit as the cue for a new one.
  • Environment design arranges space so that the desired behavior is both the most obvious and the most accessible. One should strive to dedicate each space to a single behavior.
