> It’s very difficult to intentionally find time to be bored.

I have headphones present constantly for the opposite reason. When doing tasks that fail to provide interest (housework, some work tasks) the external stimulus stops me distractedly finding something else (posting on HN for instance!) to do instead of completing the task. Also when running in town, though I don't need it when out on the trails as the scenery is more than enough to sooth my mind into a pleasant state.
