How to stop overthinking every decision
Overthinking is not extra thinking, it is thinking that has stopped producing new information. The fix is a stopping rule: decide in advance what would settle it, then stop when you have that.
What to actually weigh
Set the stopping rule first
Before you research, write down what evidence would decide it. Without that, more information just extends the loop.
Sort reversible from irreversible
Most decisions can be undone at moderate cost. Those deserve speed. Reserve the agonising for the ones that genuinely cannot be walked back.
Notice what the thinking protects you from
Deliberation postpones the moment of being responsible for a choice. If new facts stopped changing your answer a while ago, that is what is happening.
Frequently asked
Why do I overthink every decision?
Usually because deciding means accepting a loss, and continuing to think keeps that loss theoretical. The thinking feels productive precisely because it delays the cost.
How do I stop second-guessing myself?
Write the reasoning down at the moment you decide. Second-guessing thrives on a forgotten rationale — re-reading why you chose is faster than re-deciding.
