Episode: E56 – How to Get More Mileage from Your Brain
Date: March 25, 2026
Host: Dr. Christopher Camp
Guest: Dr. Amit Sood, Executive Director, Global Center for Resiliency and Well-Being

Episode Overview

This episode explores how to “get more mileage” from your brain—balancing the desire for higher performance with the essential need for rest, wellness, and meaning. Dr. Amit Sood, a renowned expert on resilience and well-being, joins Dr. Christopher Camp to break down why we often feel mentally inefficient, why it’s so hard to stay focused, and actionable strategies for optimizing cognitive performance while enhancing quality of life.

Key Discussion Points & Insights

1. Defining “Mileage” for Your Brain

• Beyond IQ and Memory: Mileage isn’t about memorizing facts or having raw brainpower. It’s about maximizing meaningful experiences, gathering wisdom, deepening relationships, and contributing to the world. (02:20)
  • Dr. Sood: “The whole idea is to add more life to your years instead of just adding years to your life.” [02:32]
• Peak and Authentic Experiences: Impact, not just efficiency, matters.

2. What Drains Cognitive Energy?

• Distractions: A long list—news cycles, financial worries, workplace stress, social pressures. (04:34)
• Default vs. Intentional Mode:
  • We often lack awareness about what occupies our mind.
  • Metaphor: Like choosing from a menu—we seldom “choose” our cognitive inputs; the brain reacts automatically, often defaulting to negativity and threat detection.
  • Notable Quote: “If you leave your mind as is to its default state, it’s going to tell the server, get me the yuckiest food... Those are the kinds of thoughts our brain thinks instinctively because we have a huge negativity bias.” [05:20]

3. Operating Modes of the Brain

• Automatic (Default) Mode:
  • Wandering, ruminative, not under conscious control; inherited from ancestors for survival.
  • Everyday Examples: Spacing out in conversation, mentally absent at meetings, distracted driving.
  • “Most of the animals are driven by automatic mode of the brain… That is the automatic brain. That is brain, where your attention is just downstream. It is not in your control.” [07:06]
• Focused (Intentional) Mode:
  • Conscious, value-driven attention.
  • Choosing to be present, to forgive, to act according to purpose (e.g., engaging with a child, listening attentively to a patient).
  • Human specialty: “When you are fully human is when your focus mode or intentional mode is active.” [08:58]
• Estimated Split:
  • Most people spend 60-80% of time in default mode—much more than even a decade ago, related to “open files” (unresolved thoughts/tasks) and rapid technological development. [10:09]
  • Outcome: The more successful we become externally, the more prone to anxiety, depression, and dissatisfaction we become internally. [11:36]

4. Why Is It So Hard to Focus?

• Evolutionary “Negativity Bias”:
  • Ancestors survived by assuming the worst; this trait persists in emotional self-defense, making us highly sensitive to perceived threats and negative feedback. [19:19]
  • Quote: “We have this negativity bias because for our ancestors, it had survival value, and it continues to have survival value for us if you are in a forest kind of situation.” [20:43]
• Wandering Attention:
  • Our brains are designed to scan for threats, and now internalize those threats—resulting in persistent worry and mental fatigue. [16:47]
  • Quote: “You roll a rock, it’s like gravity. It just goes down. You leave yourself to default, you will have wandering attention.” [17:36]
• Cognitive Fatigue’s Physical Impact:
  • Mental exhaustion triggers overeating, links to metabolic syndrome, and has downstream health consequences.
  • Quote: “When you are ruminating a lot… you experience cognitive fatigue… and that is what actually predisposes to metabolic syndrome, weight gain, and you know, all those downstream consequences.” [13:44]

5. Role and Limits of Default Mode

• Not All Bad:
  • The default mode is essential for imagination, divergent thinking, and daydreaming. The problem is overuse.
  • Quote: “Default is absolutely needed. In the right dose. And off late, that dose has increased. And what we’re trying to do is just decrease the dose of the default mode.” [15:03]

6. Lifestyle Synergy

• Sleep, Nutrition, Exercise:
  • Brain performance (and self-regulation) is tightly coupled to physical health.
  • Fatigue reduces willpower and increases reactivity—highlighting the interconnectedness of mind-body practices. [21:45]
  • “All of these unhealthy lifestyles predispose to willpower depletion… It needs energy, and that is inhibitory control, which is a core executive function.” [22:19]
• Positive Feedback Loop:
  • Improving focus empowers better health habits; better health habits enable stronger focus. [24:45]

7. Overthinking: Default or Focused?

• Overthinking is Default Mode:
  • It’s not true focus; it’s being swept along by uncontrolled thoughts, often due to uncertainty or unclear values.
  • Quote: “Am I choosing my thoughts or is thinking happening to me? When you’re choosing...then you are in the focused mode. When thinking is happening to you...that is your default mode.” [26:42 & 28:34]

Action Steps & Solutions (What You Can Do Right Now)

Dr. Sood’s Three-Step Framework [29:34]

1. Awareness:
   • Know your brain’s patterns, your role as a human and individual, and your context in the world; “converting your knowledge into wisdom.”
2. Attention:
   • Be intentional about what you focus on. Acknowledge what’s happening, then consciously “choose what is on your table,” allowing in the nurturing and meaningful, not just the urgent or negative. [29:34]
3. Attitude/Mindset:
   • Cultivate the “Big Five” values:
     • Gratitude
     • Compassion
     • Acceptance
     • Purpose
     • Forgiveness
   • Structure them throughout the week: e.g., Mondays for gratitude, Fridays for forgiveness.

Quote:
“With these awareness, attention and attitude and these principles, 98% of life’s challenges actually can soften a little bit. The tea is bitter. This is putting honey in that tea. Because I want to drink the tea. I don’t want to throw it away. The tea of life, right?” [31:44]

The “RUM” Practice for Daily Brain Optimization [34:40 & 36:54]

• R — Rest:

  • Not just sleep, but cognitive rest—pausing rumination, planning, and simply immersing in the present
  • “Rest is when you can let go of planning and problem solving, when you can completely be immersed in the moment.” [37:31]

• U — Uplifting Emotion:

  • Seek out joy—both dopamine boosts (novelty, excitement) and oxytocin experiences (compassion, forgiveness, connection)
  • “There is enormous joy in compassion, forgiveness, acceptance, pursuing purpose, experiencing flow.” [39:34]

• M — Motivation:

  • Align your actions with intrinsic goals and service to others—strive for positive impact, not just self-betterment.

Practical Takeaways

• Gratitude Practice:
  • Start your day expressing silent gratitude to important people in your life—before engaging with the world or technology. [34:40]
• Micro-Rest “RUM Moments”:
  • Infuse short moments throughout the day to reset emotionally and mentally, not just physically. (Dr. Sood’s metaphorical “sipping rum”) [34:40]

Monitoring Your Progress [45:12]

• You’re on the right track if you notice:
  • Increased proportion of positive emotions, laughter, and lightness
  • Greater engagement, less cynicism/irritability, deeper personal connections, and a feeling of purpose

Challenge to the Audience

For the next week, pause at least once per day and ask yourself:
“Am I choosing my thoughts, or is thinking happening to me?”
Use this awareness to gently redirect your attention, practice intentionality, and nurture your brain with rest, uplifting emotions, and service-driven motivation.

Closing Thought
Human optimization isn’t just about doing more or less—it’s about making every thought, emotion, and action count towards a more meaningful, connected, and joyful life.
