The "Already Decided" Trick for Stopping Overthinking

The Problem

You made a decision hours ago—maybe you sent an email, had a conversation, or committed to a plan. It's done. But your brain won't let it go. You keep replaying it. "Should I have said that differently?" "What if they took it the wrong way?" "Maybe I should have chosen the other option."

This mental replay feels productive, like you're being thorough. But it's not. You're not gaining new information. You're not solving anything. You're just burning energy re-examining something that can't be changed. It's a loop with no exit.

The Quick Fix

The "Already Decided" trick uses a simple phrase to interrupt the rumination loop and redirect your attention.

1. Catch yourself replaying. Notice when you're rehashing something that's already happened—a conversation, an email, a choice. Name it: "I'm looping."
2. Say (out loud or in your head): "Already decided." That's it. Just those two words. It's a verbal full stop.
3. Don't engage with the thought. Your brain might offer a "but what if—" Respond with "Already decided" again. No debate, no analysis.
4. Redirect to something present. Ask yourself: "What's in front of me right now?" Look around. Notice something physical. The loop can't sustain itself if you're attending to the present.

Why It Works

Overthinking persists because your brain treats past decisions as still open. "Already decided" explicitly closes the loop—it reframes the situation from "ongoing deliberation" to "completed action." The phrase is short enough to use in the moment and definitive enough to shift your mental state. Combined with redirecting to the present, it breaks the rumination cycle before it builds momentum.
