How do I stop second-guessing every decision I make?
Short answer
Make the call, write down why you made it, and review it in 30 days. You'll learn faster and stress less than replaying it nightly.
Decision journal
One sentence per decision: what you decided, why, what you expected. Almost nobody does this. Owners who do report cutting decision stress by half within a quarter.
Most calls are reversible
Hiring, pricing, marketing tests, vendor changes, almost all are reversible inside 90 days. Treat them like that. Save the agonizing for the rare one-way doors.
