How to stop thinking about something

TL;DR

To stop thinking about something, put a little distance between you and the thought, break the loop with action, and change your setting so your mind can reset. Talk to yourself by name or as "you" so you see the worry from the outside, pick the smallest next step and do it instead of turning the problem over, and step away for a walk or a different task so your brain can let the thought go on its own.

One of the most reliable ways to quiet a thought is to step outside of it. Psychologist Ethan Kross, who studies the voice in our heads, explains that talking to yourself in the third person, using your own name or "you" rather than "I," creates enough distance to look at the worry calmly, the way you would talk to a friend with the same problem. That small shift turns "why can't I let this go" into "why can't you let this go," which takes some of the heat out of the loop.

Sometimes the move is to stop trying to think about it at all. Engineering professor Barbara Oakley describes how your brain has a focused mode and a looser "diffuse" mode, and that deliberately stepping away, going for a walk, taking a shower, or sleeping on it, lets the diffuse mode keep working on the problem in the background while the conscious churning stops.

If the thought keeps circling because you have not acted on it, the way out is movement. Entrepreneur and coach Leila Hormozi points out that overthinking tends to fill the space where a decision should go, so the fix is to choose the smallest next step and take it, or give yourself a short deadline to decide, which starves the loop of the time it needs to keep spinning.
