Life is an incessant reassembling of our existing habits, because as we live we encounter new problems, and the old habits never fit perfectly. Of course as we respond to a situation with an existing habit we make that habit more likely to occur again with similar stimuli, but both the stimuli and the habitual response elicited will be a little different.
Another factor is where your mind’s attention is at when the stimulus occurs, and that is controlled by the story your mind is processing in the moment; it is the story that makes the storyteller so potent, because by the subtlest of inflections he changes the viewer’s response to the story. But it is the setup that guides the response, as much as the final stimuli, if that is what is in the viewer’s perception.
Some of these responses that come from our inner being can be intentionally controlled by the details we choose to attend to, and by the positions we choose to place our body in and the expressions we place on our face. These aspects of our being are partially under our control, and by controlling several of them at one time we can control our body’s response and our emotional responses too.
We are masters of our fate only when we consciously control our perceptions and our body’s expressions.
