Audit the role of each tool
Ask whether the tool is the source of truth, a temporary workspace or only another place to check.
Create defaults
One calendar, one main task list and a small number of clearly defined note spaces can reduce search and duplication.
Remove unnecessary alerts
Notifications should represent events that deserve interruption, not every available update.
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.
