I see. I love the process of going with the flow (going downstream), accepting life exactly as it is and exactly as it isn't.
One of the ways I do that is to recognize how my habitual negative thought patterns are actually resistant to that flow -- and that deliberately thinking thoughts that feel good when I think them (downstream thoughts), I am allowing and being the source of flow, at the same time. That's more feeling good. I would rather be flow than resistance, because it feels better.
One of the habitual negative thought patterns that interferes with flow is: resignation. "That's just the way I am. That's just the way the world is." That might sound within the bones of your head like going with the flow, but it's really resignation -- it is resistance to your own astonishing power to feel good.
