Choose a stable cue
A cue such as finishing breakfast or opening your laptop is more reliable than “when I feel motivated.”
Keep the added action small
The technique works best for a tiny behavior, not an entire productivity routine disguised as one habit.
Drop habits that add no value
If the stacked action becomes maintenance with no benefit, remove it rather than protecting the streak.
This site discusses planning and work habits, not medical treatment or diagnosis. Persistent attention, sleep, stress, or health concerns deserve support from a qualified adult or health professional rather than a productivity hack.
