The goal is simple: start the day oriented without checking every place where work can find you.
A useful daily brief does not tell you everything. It tells you what deserves your attention.
A strong brief usually answers four questions:
Depending on your work, you may also want today's meetings, deadlines, or project risks.
Use only the sources that matter for your day. For example:
Do not add a new tool just to build the brief. Start with the systems you already use.
Use an instruction like:
Review the sources available to you and orient me for today. Prioritize items that require my judgment, action, or awareness. Separate the brief into: Needs me today; Important changes; Waiting on others; Can wait. Include the source or evidence for anything you flag. If you are unsure whether something matters, say so instead of guessing.
