Lesson 1 the Brain

"As the brain directs, the body obeys. Control your thoughts, and you control your life."

Introduction

The human brain is arguably the most powerful and mysterious organ in the entire body. It weighs about 1.3 to 1.4 kilograms—just around 2% of your body weight—but it consumes over 20% of the body's energy. Why? Because it is the master controller. Every heartbeat, every blink, every word you speak, every emotion you feel, every dream you have, every solution you think of, originates from this command center. The brain is both your steering wheel and your engine. It drives you. And until you understand how it works, you may keep living as a passenger in your own body.

Think of the brain as a highly complex computer, only far more advanced than any man-made machine. But unlike a regular computer, your brain can feel, dream, imagine, grow, and even rewire itself.

Understanding your brain is the first step in mastering your life.

The Brain's Structure

The brain is divided into three major regions:

The Cerebrum: The largest part, divided into two hemispheres (left and right), responsible for higher functions like reasoning, emotions, learning, and voluntary movement.

The Cerebellum: Located at the back of the head, below the cerebrum, it controls coordination, balance, and posture.

The Brainstem: This connects the brain to the spinal cord and controls involuntary functions like breathing, heart rate, and digestion.

Each part has its unique responsibilities. While the cerebrum helps you think and plan, the brainstem keeps you alive without asking for permission.

The Four Brain Lobes and Their Roles

Each hemisphere of the cerebrum is divided into four lobes. These lobes are like departments in a company, each with a specific role.

Frontal Lobe: Responsible for decision-making, planning, behavior, emotions, and personality. It's your CEO. It helps you set goals, judge right from wrong, and think logically.

Parietal Lobe: Processes sensory information—touch, temperature, pain—and helps with spatial orientation

Occipital Lobe: Dedicated to vision. Everything you see is interpreted here

Temporal Lobe: Handles memory, language, and hearing

Understanding this can help you develop skills more consciously. Want to improve your memory? Exercise your temporal lobe. Want to build better self-control? Train your frontal lobe.

Neurons: The Brain's Messengers

Your brain contains about 86 billion neurons—specialized cells that transmit electrical and chemical signals throughout your body. These neurons form networks and "talk" to each other via synapses using neurotransmitters like dopamine, serotonin, and acetylcholine.Every thought you have is the result of a neural connection. Every habit you build is a well-worn neural pathway. Want to break a bad habit or learn something new? Then you must rewire your brain—literally.

Left Brain vs. Right Brain

Though both hemispheres work together, they are known for their specialties:

LeftBrain: Logical, analytical, language-driven. It deals with numbers, reasoning, and step-by-step tasks.

RightBrain: Creative, emotional, visual. It processes music, imagination, and holistic thinking.

You're not limited to one side. Great thinkers develop balance—logical reasoning with emotional intelligence, discipline with creativity.

The Subconscious Mind

Beneath your conscious awareness lies the subconscious mind—a powerful storehouse of habits, beliefs, memories, and emotional responses. It's estimated that over 90% of your daily actions are driven by your subconscious mind.

This is why someone can say "I'll stop smoking" or "I'll start waking up early," but without reprogramming the subconscious, nothing changes.Affirmations, visualization, meditation, and repetition are tools to communicate with your subconscious.

Note: You don't rise to the level of your goals—you fall to the level of your programming.

Neuroplasticity: You Can Change

Once upon a time, scientists believed the brain stops growing after childhood. But modern science has proven that the brain remains flexible throughout life—a quality called neuroplasticity.

What does this mean?

It means you can:

Learn new skills at any age

Unlearn toxic patterns

Recover from trauma

Reinvent your identity

Neuroplasticity is hope. Your past does not define your future. Your brain is not a rock. It's a garden. What you plant and water will grow.

Emotions and the Brain

Emotions originate from deep parts of the brain like the amygdala and hypothalamus. These areas detect threats, interpret experiences, and release chemicals that make you feel joy, anger, sadness, or fear.

When fear dominates the brain, logic shuts down. This is why a panicked person can make poor decisions. Learning how to calm your mind through breathing, journaling, or prayer gives your thinking brain a chance to lead.

Note:Emotions are signals, not commands. Feel them, but don't be ruled by them.

How Foods and Fruits That Help the Brain

Examples of Brain-Boosting Foods

These can be plant-based or animal-based:

1. Eggs – high in choline, which supports memory and brain development.

2. Fatty fish (salmon, mackerel, sardines) – rich in omega-3 fatty acids for brain cell health.

3. Nuts & seeds – contain healthy fats, vitamin E, and minerals for nerve function.

4. Whole grains – steady energy supply for the brain.

5. Dark chocolate – improves blood flow and focus due to antioxidants and caffeine.

6. Green leafy vegetables (spinach, kale, broccoli) – rich in brain-protecting vitamins and minerals.

Examples of Brain-Boosting Fruits

These are naturally sweet plant products:

1. Blueberries – high in antioxidants, help with memory.

2. Oranges – vitamin C to protect brain cells from damage.

3. Bananas – provide potassium and glucose for quick brain energy.

4. Avocados – healthy fats for blood flow to the brain.

5. Grapes – antioxidants improve memory and learning speed.

6. Pomegranates – protect brain cells from oxidative stress.

When the Brain Is Most Effective

People often say the brain works best between 4:00 AM and 7:00 AM — here's why:

Early morning hours (especially after good sleep) are when the brain is fresh, well-rested, and distraction-free.

During this time, cortisol levels are naturally higher — this hormone boosts alertness.

The prefrontal cortex (responsible for focus and problem-solving) is more active right after waking.

In many cultures, early mornings are called the "golden hours" for studying, meditation, and creative work.

📌 However:

Peak brain performance also depends on your personal body clock (chronotype).

Morning people ("larks") peak earlier.

Night owls might be sharpest in late morning or even at night.
