12. Stop hanging out with energy vampires.

Do you always feel drained after hanging out with them?

Then limit your time with them.

11. Eat like your future kid is growing inside you.

Ask yourself: would this meal build a healthy brain?

10. A shredded body with a shattered soul isn't health.

Your mind needs exercise just as your body does:

• be in nature
• meet friends
• visit your family
• travel the world
• challenge yourself
• create beautiful memories

9. Practice saying "no" at parties.

Not to be antisocial — to learn impulse control.

8. Fall in love with boredom.

Don't take out your phone.

If you can sit with boredom, you’ll beat addictions before they start.

7. Good sleep is the foundation of a healthy body & mind. 

Here's how to fix it:

• No caffeine after noon
• Be outside & get sunlight
• Stop eating 2-3h before bedtime
• Sleep/wake up at the same times
• Never try to catch up on lost sleep
• No screen at least 1h before bedtime

6. Dating apps amplify loneliness.

These apps aren't designed to find you a partner.

They're designed to make you use the app.

5. Comfort is the archenemy of progress.

The best way to stay stuck & depressed is to always do what feels comfortable.

4. Porn destroys your brain and makes you depressed.

3. The best longevity & anti-aging hack is muscle training.

Here's how:

• sleep at least 8h/day
• limit processed foods
• track your progress weekly
• creatine monohydrate: 5g/day
• increase weights in small steps
• train each muscle group 2x/week
• eat 1g of protein per lbs body weight

2. Movement is the most underused anti-depressant.

Walks in nature are the healthiest habit you can adopt.

I'm 30 and have a PhD in healthcare research.

If you're in your 20s or 30s read this:

1. Fast food is the most dangerous drug in the world.

No joke: Chewing gum beats stress.

It lowers your stress hormone and reduces anxiety while boosting alertness.

13. Live a life that is true to yourself.

Most of us do what society/family/friends expect from us.

They mean no harm, but sometimes their dreams must die for yours to live.

Live an authentic life that is a true reflection of who you are.

12. The number of close relationships is even more important for your health than losing weight or stopping smoking.

Our social circle is the number one predictor of living a long life.

So, build as many meaningful connections as you can.

11. Do small things that suck every day (micro sucks).

Your willpower is like a muscle — it can be trained.

Consistently doing things you don’t want to do is the best way to strengthen it.

10. Go to the NEAREST gym.

Forget about price, benefits & equipment.

Pick the gym closest to your home.

A long distance between gym and home creates a mental barrier.

9. Remove all clocks from your bedroom.

The first thing you do when you wake up during the night is check the time.

This triggers a stress response in your brain — which makes it harder to fall back asleep and reduces sleep quality.

8. When you’re hungry don’t eat — drink a big glass of water.

Our brains often mistake thirst for hunger.

If you’re still hungry after 15 - 20 min, you know it’s real hunger.

7. Don’t aim for happiness.

Aim for inner peace.

What brings you peace is often uncomfortable but leads to a much more fulfilling life.

6. Don’t track your calories/weight/sleep every day.

You’ll be much more consistent if you focus on tracking every week.

5. Don’t drink coffee after noon.

Caffeine stays in your system much longer than you think.

Even if you fall asleep easily the quality of your sleep decreases.

4. Muscle training is more effective than any anti-aging cream.

3. Alcohol is poison.

If you drink, drink in moderation.

Don't believe those "wine is healthy" claims.

2. Stress isn't bad for you.

Your perception of stress is what matters.

If you believe stress is good for you, it’ll help you grow and become more resilient.
