Think in public.
Revise in private.
Good thinking is not a personality trait. It is a set of habits that makes your reasoning visible enough to examine.
State the actual decision.
“Should I change jobs?” may hide several different decisions: whether to look, what income is required, whether to change roles, and when to act. Write one decision in terms of a choice you can make and a time by which you need to make it.
Complete: “By [date], I need to decide whether to [action] or [alternative], because [reason].”
Separate data from interpretation.
Make two columns. Put direct observations, numbers and documents on one side. Put predictions, explanations and feelings on the other. Feelings matter; they are just a different kind of information. Ask what credible alternative story fits the same facts.
What evidence would you expect to see if your current explanation were wrong? Who could tell you something that you do not already know?
Reduce uncertainty before committing.
A short conversation, small prototype, limited trial or second quote may answer a more useful question than another hour of debate. Set a learning goal and a date to revisit. Some choices are irreversible or urgent; in those cases seek relevant expert advice rather than forcing a small experiment.
“If I do [small action] this week, I will learn [important unknown]. I will reconsider on [date].”
