can you explain "limbic friction"

Limbic friction is the effort it takes to shift your body and mind from an autonomic state that doesn’t fit what you want to do—either too alert or too tired—to one that does. 1

• Too alert: Anxiety, stress, or distraction can make it hard to calm down enough for an activity that calls for a quieter state. 2
• Too tired or underactivated: Fatigue or low motivation can make it hard to become alert and get started. Both directions—calming down and becoming more alert—can require effort. 3
• Habits and conscious effort: When a habit is new or difficult, you may need to consciously override your body’s current state to do it; as the habit becomes more automatic, that effort tends to lessen. 4
