A check
A worry turns up at ten in the morning and your slot is at six. What does the appointment ask you to do?
Push the thought away and refuse to have itSolve it now so it does not come back laterWrite it down in a line and carry on, and take it to the slotDecide whether it is a reasonable worry first
Yes
Not pushing away, because that does not work and it makes you monitor for the thought. Not solving, because the worries that respond to solving are jobs and the rest do not respond to solving at all. And not judging whether it is reasonable, because that is a debate and the debate is the thing that eats the day. Write it, and go back to what you were doing.
