Tasks and notes are related, but they are not the same. A task is something to do. A note is information to keep. Separating them makes both easier to review.
Write tasks as actions
A useful task starts with a verb, such as call, send, review, buy, or schedule. This makes the next step clearer when looking at the list later.
Store supporting information in notes
Long explanations, links, meeting notes, and documents can live in apps such as Google Keep, Evernote, or Notion. The task list can link mentally or explicitly to the related note.
Review regularly
Weekly review helps remove finished, duplicate, or outdated items. It also reveals whether too many apps are being used for the same purpose.
