"Your thoughts create inner standards or rules that spark neurochemical dynamic processes, which selectively govern your choices and actions with precision.
It takes a thought to spark an emotion, or drive a decision to take an action or to take no action at all. And emotions give meaning to thoughts; they are the spark. In the words of neuroscientist Antonio Damasio, are “a telltale sign of consciousness.”
Toxic thinking is self-perpetuating. It not only stimulates the body’s reward or learning centers with pseudo feel-good feelings, it also activates the body’s fear response, which further increases the likelihood that the defensive behaviors it triggers will be repeated.
Unless you set an intention to make conscious changes, more often, change that occurs at subconscious levels tends to be self-perpetuating.
In other words, if you do not have the life and relationships that you want, you likely do not have the thinking patterns you need to create the optimal emotional states, and thus actions, that would sustain your momentum in the overall direction of your aspirations."
