You replay a conversation from three days ago. You rewrite a two-line message five times before sending it. You lie awake running through every way tomorrow could go wrong. Overthinking doesn't feel like a choice. It feels like your brain has a mind of its own.
The good news is that you don't need to "just stop thinking". You need a routine that gives your thoughts somewhere to go. Below is a 10-minute daily method you can start today, plus what to do when overthinking hits outside that window.
What overthinking actually is
Thinking is useful. Overthinking is thinking that goes round in circles without producing an action, a decision or any real relief. Psychologists often split it into two patterns:
- Rumination: going over the past. "Why did I say that? What must they think of me?"
- Worry: rehearsing the future. "What if I mess up the interview? What if they say no?"
The late psychologist Susan Nolen-Hoeksema spent much of her career studying rumination. Her research suggests that repetitive, passive dwelling tends to keep low mood going rather than solving anything. The key word is passive: you're turning the problem over without moving it forward.
So the aim isn't an empty mind. The aim is to turn loops into either a decision, an action or a deliberate "let it go".
The 10-minute daily method
Do this once a day at a set time. Late afternoon or early evening works well for most people: late enough to catch the day's worries, early enough that it doesn't feed into bedtime. You need a notebook and a timer.
Minutes 0–3: Empty the loop
Set a timer for three minutes and write down every thought that has been circling today. Don't organise or judge them. Short fragments are fine:
- "Did I sound rude in the team meeting?"
- "Need to reply to Mum about Sunday."
- "What if the rent goes up?"
Getting thoughts out of your head and onto paper makes them smaller and more concrete. Something that felt enormous at 2pm often looks quite manageable written in biro.
Minutes 3–6: Sort each thought into one of three boxes
Go down your list and mark each line with a letter:
- A = Action. There's something I can actually do. ("Reply to Mum.")
- D = Decision. I need to choose between options. ("Take the job or not?")
- L = Let go. I can't change it, or it's not mine to solve. ("What they thought of my joke.")
This single step is where most of the relief comes from. Overthinking treats everything as an open problem. Sorting shows you that many loops have no action attached, and some have a very small one.
Minutes 6–9: Give each box a next step
- For every A, write the smallest next step and when you'll do it. "Text Mum at 7pm: yes to Sunday lunch."
- For every D, write a deadline and the one piece of information you're missing. "Decide by Friday. Need: the salary figure in writing." For bigger choices, the Decision Making Prime Protocol walks you through it.
- For every L, write one kind sentence and cross it out. "I said what I said. Most people have already forgotten it."
Minute 9–10: Close the notebook
Say to yourself, "That's handled for today." Then physically close the notebook and put it somewhere you can see it. You're teaching your brain that there is a proper place and time for these thoughts, and that they won't be lost.
Try this today
Set a phone reminder called 'Loop time' for 6pm. When it goes off, do the three-minute brain dump and the A/D/L sort. Just that. You can add the rest of the method tomorrow.
When overthinking hits outside your 10 minutes
Thoughts won't politely wait for 6pm. When one grabs you during the day, use this three-line script:
- Notice: "I'm looping on the email again."
- Park it: jot one word on a note in your phone called "For loop time".
- Return: name one thing you can see and go back to what you were doing.
Psychologist Thomas Borkovec and colleagues tested a similar idea in the 1980s, sometimes called "worry postponement". Their findings suggested that setting aside a specific daily worry period, and postponing worries until then, helped people worry less during the rest of the day. You're not ignoring the thought; you're booking it an appointment.
Three habits that make the method stick
- Keep it short. Ten minutes is the limit. If you go longer, you slide back into rumination on paper.
- Act fast on small A's. Anything under two minutes, do straight after your session. Finished tasks stop nagging.
- Review weekly. On Sunday, flick back through the week. You'll usually notice that most of what you worried about either didn't happen or turned out fine. That evidence helps next time.
If you'd like a calmer baseline to work from, pair the method with the Calm Mind Prime Protocol, which gives you a short daily practice to settle your nervous system.

What to expect
For the first few days your list may be long and messy. That's normal. Within a week or two, most people find the list gets shorter and the loops lose some of their grip, simply because they're being dealt with instead of replayed. Some days you'll forget. Just pick it up again the next day.
Start today
Grab any notebook, set a reminder for this evening and do one round of the method: dump, sort, next step, close. Then read your Prime Affirmations aloud before bed. For a steady daily routine, try the Mental Clarity Prime Protocol.
