I'm 63.

I blamed age for slowing down...

But age wasn’t the issue.

Something deeper was silently draining me.

Here are 7 ways to stop burnout, cure anxiety, and conquer depression. (before it becomes irreversible!) Image
Image
You’re not lazy. You’re not broken.

Your SEROTONIN is low, and it’s destroying your mental health.

It’s the hidden reason you feel burned out, anxious, and depressed. Image
Healthy serotonin levels keep you calm under pressure.

It regulates your mood, focus, and energy.

When it’s low, everything feels like too much.

So, what causes low serotonin?
There are 3 ways seratonin drops and you get stuck in survival mode:

1. You start ruminating (which fosters poor sleep).

2. You eat poorly and do repetitive behaviors-like scrolling (FOMO and panic increases)

3. You stay indoor without sunlight. Image
When you feel unmotivated and lethargic..

1/ Negative self-talk starts showing up:

"I've never been organized."

"I suck at the details."

"I'm not enough."

But really, your SEROTONIN levels have dropped.

And, they drop even further because you hate on yourself.

What else is going on?Image
2/ Your gut biome's get messed up by eating sugar and processed foods.

This sabotages your SEROTONIN levels.

90% of serotonin is produced in the gut, not the brain.

Feed your gut with good microbiome: fiber-rich plants, fermented foods (like kefir, kimchi), and lots of water. Image
3/ Get tryptophan from your food. It builds SEROTONIN resources.

Pair protein-rich foods like turkey or eggs with whole grains to boost serotonin naturally and help it cross the blood-brain barrier.

Eat real, whole meals, not just crappy snacks.
4/ Get good physical exercise. It raises SEROTONIN levels.

How: Walking increases neurotrophic brain factors that stimulate serotonin receptor sites in your brain.

You don’t need the gym.

Walking outdoors for 30 minutes or more changes everything.
5/ Get plenty of good sleep.

Your body builds serotonin resources during the day, but converts it to melatonin at night.

Poor sleep disrupts this cycle, lowering both mood and sleep quality.

Try to go to bed and wake up at the same time daily.

9 -10 hours of excellent sleep is optional.

Most of us get far less.

Try to catch a 9-hour sleep day at least once a week.
6/ Sunlight is critical to regulate SEROTONIN levels..

Serotonin is made from tryptophan, but ONLY when your body gets sunlight.

Sunshine helps regulate serotonin through the skin and eyes (via vitamin D synthesis and circadian rhythms)

Your brain converts tryptophan into serotonin, stabilizing your mood and lowering your anxiety.

Even 15–30 minutes outside daily will shift your mental state.Image
7/ Neuroscience proves mental overload depletes SEROTONIN levels.

Mental overload happens when you're constantly scrolling social media, task switching, and attending to endless beeps and notifications.

All of these scattered activities make it harder to achieve mental rest.

And, mental rest --where you put your phone down, close your computer, and take a device break--restores SEROTONIN levels naturally.

Block out 30 minutes a day for stillness or walking outdoors without devices.
Natural ways to elevate SEROTONIN are everywhere.

You don't need to depend on meds like SSRIs -- Prozac or Zoloft.

Take advantage of the power of nature, good food, rest, and sunlight. Image

In my 30s and 40s...

• I made reckless choices.
• Anxiety trapped me for years.

Then I found Martin Heidegger.

He taught me how to stop living FALSELY.

Here’s his 4-step protocol for mental freedom: 🧵 Image
Heidegger was a philosopher and when anxiety hit, his
Salience Network (SN) yelled: “Something is off.”

He also noticed he was spinning false stories:

“What does this mean about me?”
"Why am I a loser?"

(His DMN was activated)

But then he did something very different.

He observed his thoughts.

And, by observing, he came up with a cure for 21st century anxiety:
(I'll summarize below...)
Step 1: Treat anxiety as a signal, not a symptom.

Don’t ask: “How do I stop this?”
Ask: “What false life is being exposed?”

Practice (60 seconds):
Name it plainly:
“This anxiety is pointing at ____.”

One sentence. No spirals. Image

The most influential psychologist of the 20th century wrote private letters to his children.

They weren’t about therapy.

They were about how to survive being human without losing your soul.

Here are 9 principles Carl Jung QUIETLY taught his children—that most people never hear about: 🧵Image
First, understand who Jung was:

• Medical doctor + psychiatrist
• Founder of analytical psychology
• Broke with Freud at the height of his career
• Studied myth, religion, alchemy, and dreams
• Treated world leaders, artists, and thinkers

But his most radical work wasn’t in books.

It was in how he taught his children to live.Image
Principle 1: “Do not become what the world wants from you.”

Jung warned his children that society rewards adaptation—but punishes authenticity.

“If you live only as you are expected, you will become empty.”

The task wasn’t to be successful.

It was to become whole.

The most powerful metaphor about the human mind:

Plato's Cave.

It explains why most people feel stressed, depressed, and trapped—without knowing why.

Here are 7 warning signs + the exit protocol 🧵 Image
Plato imagined prisoners chained in a cave since birth, facing a blank wall.

Behind them: a fire casting shadows from puppets.

The prisoners believed these shadows were reality because it's all they've ever known.

This isn't ancient philosophy - it's your daily life--RIGHT NOW.Image
Sign #1:

You react with hostility to ideas that challenge your worldview.

When information contradicts your beliefs, do you feel angry rather than curious?

That's your chains rattling.

True seekers say "that's interesting" instead of "that's wrong" when confronted with new perspectives.

The hidden cause of chronic anxiety, people-pleasing, and “always on” stress:

Self-abandonment.

Warning signs appear long before panic attacks or burnout.

Here are 5 early signs to watch for (share this with someone you love) 🧵

Dread before social situations Image
It’s not “introversion.”

It’s your nervous system running an old risk calculation:
“If I’m fully myself, I could lose connection.”

So your body goes into threat mode—before you even walk in.

Ignore this, and the next signs get harder to miss… Image
2. You hesitate right before telling the truth

That pause isn’t shyness.

It’s protection.

Your system learned early:
Truth can cost love.
So it tries to keep you safe by silencing you first.

Once your body treats honesty like danger, what do you do?

CO₂ sensitivity is one of the most powerful (and ignored) nervous-system interventions.

But, most people don’t know this system exists.

Here are 7 ways to calm your CO₂ alarm + lower your anxiety (in seconds).🧵
1. Stop “silent overbreathing.” Image
Image
Most anxious people aren’t breathing too little.

They’re breathing TOO MUCH (fast, shallow, chest-only breathing).

That keeps your chemoreflex on a hair trigger.

Instead:

breathe quieter
breathe lower (belly/ribs)
slow your pace
2. Lengthen your exhale.

This instantly downshifts your nervous system's thread detector.

Slow breathing with longer exhales reduces nervous system anxiety and shift body stress within minutes.

Try:

Inhale 4 seconds → Exhale 6–8 seconds

Do 6 cycles at first.

Ernie Hudson is 80 years old.

And he looks stronger than most men half his age.

His secret?

No “get shredded in 30 days"...

Just repeatable systems he’s followed for years: Image
Image
He basically treats physical fitness like mental fitness:

Small reps.
Daily repetition.
No drama.

And that’s why it lasts decades.

The lesson?
Consistency beats intensity.

A system you can run for 20 years beats a “transformation” you quit in 20 days.

Your body and mind are your responsibility.

Hudson says, "Build habits that compound."

At 30 you call it “fitness.”

At 80 you call it freedom.
