This document discusses possibility thinking and how our minds process experiences. It defines possibility thinking as the ability to manage attention and make proactive choices regardless of stressful circumstances. It describes how the amygdala processes threats and alerts the hippocampus and brain stem. A highly reactive "hot" amygdala reduces problem-solving abilities. When the amygdala remains quiet during non-threatening experiences, higher-level thinking in the prefrontal cortex is possible. The document contrasts the mind states of expansion, associated with enthusiasm and opportunity, versus contraction, associated with guardedness and isolation.
