When you focus all your attention on writing about your thoughts, it makes you slow down.
While writing, you can’t think about a few thoughts simultaneously.
Only one thing.
This brings you into the here and now at this moment.
You start looking at your thoughts more objectively, which calms you down.
This way, you start recognizing patterns in your thinking.
You externalize overthinking into a paper, making your mind calmer and more organized.
From there, you can step on the way of thinking differently about events,
problems, and decisions.
After that, it is easier to make the required change if necessary.
