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

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.

Anxiety isn’t overthinking.

It’s your brain reacting to uncertainty...
and your soul reaching for freedom.

I condensed Kierkegaard into 4 moves. Use this when anxiety spikes.🧵
At 21, Kierkegaard watched his 5th sibling die.

By 30, he was engaged, famous, and set for a conventional life—

Then he detonated it.
He broke off the engagement.

Rejected the “safe path.”

And wrote the line that explains modern anxiety better than most therapists:

“Anxiety is the dizziness of freedom.”

David Sinclair is a longevity expert.

But his most underrated “longevity protocol” isn’t supplements.

It’s how he keeps anxiety low in a high-pressure life.

Here's Sinclair's 6-rule system. (you don't want to miss this) 🧵 Image
Image
1. Choose stressors that make you stronger.

Stop lumping all “stress” together.

There are 2 kinds:

1. Biological stress (hormesis) that builds resilience.

2. Psychological stress that grinds you down.

They shouldn’t even share the same word.
2. Schedule “quiet time” like it’s medicine.

Not “vibe” time.
A calendar rule.

Book quiet time daily—so problems don’t hijack your nervous system.

Most people aren’t “burned out.”

They’re stuck in always-on stress.

Here are 7 ways to switch it off (without meds) 🧵

1. Stop putting your brain in scatterbrain mode. Image
When your attention is constantly yanked around, your body stays keyed up.
Even “rest” doesn’t feel restful.

Try this:
Check social 2x/day + 30 minutes phone-free quiet or device-free walking.
2. Get morning light—especially in winter.

Morning light sets your body clock, which stabilizes mood and sleep.

Try this:
10–20 minutes outside early (no sunglasses if you can).

5 personality traits that predict how you handle stress.

Find yours in 30 seconds (and how to work with it) 🧵 Image
Image
First: the Big 5 are not “labels.”

They’re your nervous system’s default strategy.

When you're aware of your default strategy, you can build on it and let it empower you. Image
Let's dive in...

1. High Neuroticism = The Threat Sensor

When you're high on neuroticism, you feel everything early, before others. You're very sensitive.

The signs of Neuroticism are:

→ overthinking
→ health worries
→ tension & rumination
→ The inner feeling: “I can’t turn this off.”

Quick fixes:

Regulate first, analyze second.
One sure-fire way to regulate is to walk outdoors without devices.
You want to downshift your alarm system. Walking is primo.

High-functioning anxiety isn’t overthinking.

It’s a nervous system that won’t shut off.

Here are 7 ways to shut it down today (for real) 🧵

1. Stop treating your thoughts like truth.
1. Thoughts aren’t facts. They’re weather.

An anxious mind doesn’t “think.”

It scans like a radar system.

1. It predicts.
2. It rehearses.
3. It builds catastrophes.

So your next move is this:

Set a timer, "chimes", that ring random times of the day.
Check in with your body.

This helps you notice if you're calm or in the fight-or-flight response.
2. Put worry in its place. (Yes, schedule it.)

High performers don’t “worry less.”

They worry all day while pretending they’re fine.

Try this:

→ 15 minutes of structured worry time.
→ When the timer ends, stop worrying.

You interrupt the unconscious worry loop.

And your day stops becoming one long internal emergency.
