Going into any uncertain circumstance without a plan is almost certain to activate the survival system.
Have a plan whenever you're dealing with uncertainty of any kind.
Having a plan gives us a far greater chance at operating objectively with the PreFrontal Cortex (planning) part of the brain, as opposed to reactively from the Limbic (survival) part of the brain.
The better we know what it is we're dealing with, the easier it becomes to deal with it.
Conversely if we don't know what we're dealing with it can feel like measuring in the dark.
Our primary operation is being driven by either the PFC, or the limbic brain at any given time, with the limbic brain always on and running, regardless if the PFC is working or not.
Learn the art of deactivating your stress response system, addressing emotions, physiology, and psychology. Take the power of mystery away from it activating, and gain the confidence knowing you can shut it down.
Muscle memorize system calming measures that work for you, so well that your body is able to do them when your mind gets knocked psychologically unconscious by stress. At some threshold this happens to all of us.
Consciously choose to exchange fear and/or anger with a sense of curiosity about anything that activated your stress response system.
Develop your ability to release the felt need to personalize the fact it activated in the first place, and simply observe the mechanics of it activating and deactivating.
Curiosity helps demystify psychological trauma, and take the power of mystery away from it, and this helps reduce as much uncertainty about what we're working with as possible.
Even a little bit of light makes a world of difference in the dark.
