The problem I have with this is that my thoughts come 10 or 20 times quicker than I can write them down. And while doing this writing exercise I’ll have meta-thoughts about the writing and the exercise. The thoughts hopelessly outrun the writing, and also the train of thoughts will be wildly different from what it would be when not attempting to write it down. I guess one still learns something from the exercise, but…
I find it very helpful to slow down, breathe, and regain connection to my body.
And you can stop whenever you want. Journaling is something you do for yourself — it shouldn’t feel like a chore.
Your journal is your safe place where you can dump your thoughts. It will never judge you :) It can receive anything you offer to it.
