Your nervous system controls productivity more than effort does. When dysregulated, your amygdala triggers a threat response that pulls blood from your prefrontal cortex, narrowing perception and killing clear thinking. Regulating your nervous system reactivates that cortex and restores peak performance.

It doesn't matter how hard you're able to work, if you cannot regulate your nervous system, you are going to be working twice as hard. Because when you're in a dysregulated nervous system state, your amygdala is firing, you're in that fear, that stress, that anxiety. All the blood flow from your prefrontal cortex, which is where you can create and think and problem solve and do all these things, it goes away. Your body and mind is in threat scanning mode, right? It's literally narrowed its perception on what's around you because it thinks it's running from a lion. So in order to perform at your best, think clearly, execute, have energy, we have to regulate ourselves so we can turn that part of our brain back on and perform at the highest level.
