Try this
- Break the proposed activity into concrete tasks, including reminders and follow-up.
- Accept only the pieces you can own. If no one takes the remaining work, reduce or postpone the activity instead of silently absorbing it.
A worked example
“I can book the table, but I cannot organize everyone’s transport too.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Assign the remaining tasks explicitly or reduce the plan’s complexity.
