How to use brain dump / capture
1. Capture in one place
Choose a notebook or simple inbox that is easy to reach.

Example: Turn the appointment note into “find the clinic phone number.”
3. Give actions a place to return
Move only useful commitments into the plan you actually consult.
Example: Add the call to tomorrow’s short list and archive the original note.
These examples are illustrative. Adjust the steps and timings to your situation.
