The spirit of this is correct, but a better approach to this is going for a walk with just your thoughts.

Yes, that means no phone, no headphones, just you and your brain enjoying a walk. Let your mind wonder and be free.

There’s a lot of research on restorative environments (usually nature/outside)being good for focus. I definitely try to spend as much time outside as I can, but for some reason the wall works better for that 5-10 minutes. Being outside is much more enjoyable though haha
