I struggle with the 'anything' part of this laundry list. It appears there are things I do have control over. Like my movement, my thoughts, my words.
Perhaps what it means is that although there are things I can control in my own sphere, in the context of my relationships with other people, in the context of my country, my planet and the universe, there isn't anything I really control.
My take-away from this is that I do my best to be aware, to consider, to make good decisions, to act. And then if things don't really go my way, there is no use getting upset or tied up about it. I have done all I can - there are so many massive movements outside of my control that it is of great benefit to me to be more like water flowing around a rock, and less like the rock.
