I would say that the majority of my meditation I do everyday consists of becoming distracted, noticing I’m distracted, going back to focusing on my breath, becoming distracted, repeating ad infinitum.
It’s about training yourself to become better at 1) noticing you’re distracted and 2) bringing yourself back into focus. It’s pretty much muscle training except for your brain, specifically on improving executive functioning.
Very little of meditation actually follows the “pure zen enlightenment” that’s commonly associated with it. Of course sometimes I do get a few minutes of that close to the end of my meditating sessions, but it’s not my main priority when I meditate and the majority of the benefits really come from the portions where I’m getting distracted and working on improving my ability to get back to focus.
