Four character defects:
PlanSchemePlot: this is where I mentally run through plans, schemes, and plots to achieve outcomes.
FixChangeControl: this is where I work out how to regulate other people's behaviour.
MoanWhineGripe: this is where I resentfully dwell on things I do not like or disagree with.
FretBroodWorry: this is where I focus on fearful or gloomy states of affairs.
When I spot these, I can remind myself: This is an outside matter on which I have no opinion.
I can then come back to the moment and the activity at hand.
