It took me a while to recognize that the reason why I feel as though I need to go for walks outside when I get upset is because it was my earliest self-discovered from of mindfulness. My dad, thankfully would recognize this too, and rather than stopping me from absconding, would just follow along with me, offering a bike or a route to take. Not much talking was usually involved though. Now a days, I live far from my family and I take myself on my own walks.
What do I mean that walking outside is an exercise in mindfulness for me?
When walking outside, I can't help but look at the nature around me, the beautiful sky, the smell of the sea, or the humming sound of insects. I let myself give into just perceiving the current state of that which is around me. In doing so, I temporarily remove myself from thoughts of past conflicts, even ones recently past, and I forget to think about my fears about the future. I go from perceiving my present environment to slowly recognizing how I'm feeling presently, but without the cast of other characters who would like to tell me how to think and feel.
From outside, I can orient myself. I can see more clearly what is a life emergency and what is not. From outside, all of the NT socialites whose worlds are so bound up in each other's opinions of one another, in their social efforts and punishments, they seem like funny little cave dwellers who can't perceive a world outside their own to me... and I feel free and content to be myself.
