I also swim four to five times a week, and once you get rolling into a rhythm of breathing and movement, your mind can truly untether, which I find so refreshing.
I have found, without a doubt, that when I manage to get outside myself and not make myself the center, I'm always taken care of in whatever situation I'm in, even if I'm slow to recognize it. It's counterintuitive thinking on some level and not consistently easy to do.
I have a lot of appetites and try to revel in almost everything, so inspiration can even come from a well-appointed submarine sandwich, you know?
Walking my dogs twice a day provides me with an opening and closing of my day, and I've learned to use those walks for a walking meditation.
