I’m 51. Here Are 31 Lessons I Wish I Knew In My 30’s.

At 30, I had already experienced the highs and lows of life. I’d made—and lost—$6 million, burned myself out chasing success, and was left wondering what I was doing wrong. Fast forward 20 years, and my journey has taken me through reversing aging, building multi-million-dollar companies, and unlocking what truly matters. Along the way, I’ve learned invaluable lessons that I wish my younger self had known. Here’s what I’ve discovered —insights that might just change the trajectory of your own life. 

1. Say No More Often

Time is your most valuable asset. Focus on what matters—your health, family, and personal growth. Say no to distractions and unnecessary obligations.

2. You Don’t Find Yourself—You Create Yourself

Stop looking for yourself. Instead, make conscious choices about who you want to be.

3. Stop Saying “Try”

Language shapes reality. Saying “I’ll try” programs your subconscious for failure. Either do it or don’t.

4. Your Beliefs Shape Your Reality

Question your beliefs regularly. If they’re holding you back, change them.

5. IQ Alone Doesn’t Make You Smart

Learning fast and applying knowledge beats having a high IQ. Learn how to learn.

6. Smart Drugs Are a Cheat Code

Nootropics and cognitive enhancers help optimize your brain. If you’re not using them, you’re leaving potential on the table.

7. Face Your Inner Demons

Whether it’s neurofeedback, breathwork, or meditation, deep self-exploration is key to growth.

8. Breath is the Most Powerful Drug

Proper breathing changes brain chemistry and enhances performance.

9. Fear of Failure Creates Failure

Failure doesn’t kill you. Fear does. Learn to control your fear and take action.

10. Average is the Enemy

Innovators are always hated at first. If you’re not pissing someone off, you’re not doing anything meaningful.

11. Push Hard, But Rest Hard Too

Burnout happens when you never rest. Balance intense effort with intentional recovery.

12. Mornings Set the Tone for Miracles

If you start your day reacting to the world, you’ve already lost. Start by focusing on yourself.

13. Master Your Sexual Energy

Redirect sexual energy into creation and mastery. Avoid porn; it rewires your brain in damaging ways.

14. Waking Up Early Doesn’t Make You a Better Person

What matters is getting high-quality sleep when your body needs it, not forcing yourself to wake up at 5 AM.

15. Sleep Quality Beats Sleep Quantity

Six hours of great sleep trumps eight hours of bad sleep. Track and optimize your rest.

16. Running a Marathon Won’t Make You Healthier

Too much cardio can be harmful. Train smarter, not harder.

17. Hunger Isn’t Always About Food

Often, hunger signals a need for love, connection, or rest—not calories.

18. Your Gut Microbiome Controls More Than You Think

Healthy gut bacteria improve mood, energy, and overall well-being. Feed them well.

19. Track What Matters

You can only improve what you measure. Whether it’s sleep, diet, or performance—track it.

20. Chronic Stress Will Kill You

Short bursts of stress make you stronger. Constant stress destroys you. Remove unnecessary stressors.

21. Money Buys Happiness—Up to a Point

After covering basic needs (around $100K annually), more money won’t increase happiness. Focus on what truly matters.

22. Happiness Creates Wealth

Happy people perform better, make better decisions, and attract more opportunities.

23. Less Stuff, More Freedom

Owning too much weighs you down. Clear space in your life for things that truly matter.

24. Your Social Circle is a Drug

Surround yourself with inspiring, growth-oriented people. Avoid toxic, negative influences.

25. Relationships Make or Break You

Love alone isn’t enough. Choose a compatible partner who supports your growth.

26. Learn the Box Breath

Navy SEALs use it to instantly reduce stress. Inhale, hold, exhale, and hold again—all for equal counts.

27. Meditate Smarter, Not Longer

You don’t need hours of meditation. Use technology and techniques that maximize efficiency.

28. Nature Unlocks Higher Performance

Urban life drains energy. Get outside, breathe fresh air, and expose yourself to natural light.

29. Gratitude is Stronger Than Fear

Gratitude shifts your nervous system away from stress. Make it a habit.

30. Forgiveness Frees Your Energy

You don’t have to tell someone what they did was okay, but letting go of resentment frees up mental and emotional bandwidth.

31. Start With Three

If this list feels overwhelming, just pick three lessons to implement today. Small changes compound into massive transformation.

Implement these lessons and see how they change your life. Who knows what you might do?

By Dave Asprey

You‘ve probably noticed a lot of talk about cooking oils and fats lately. I’ve been discussing the negative effects of seed oils for years —they’re unstable, oxidize easily, and slow down your cells. But what about olive oil? There is so much conflicting advice. Some say it’s fine to chug several tablespoons per day and use it for cooking. Others say it breaks down and oxidizes at most temperatures, so stay away. The truth, as usual, lies somewhere in between. Olive oil has many benefits if you use it right. But there are two superior options for most applications, including high-heat cooking: tallow and ghee.

Let’s dive into the science of why animal fats like tallow and ghee are better for high-heat cooking, why extra virgin olive oil (EVOO) has limitations, and how to use olive oil without losing its health benefits—or damaging your biology.

The Oxidation Problem: What Happens When Unstable Oils Meet Heat

When you heat cooking oils, their fatty acids can oxidize, meaning they react with oxygen to form harmful compounds like lipid peroxides [1]. These oxidative byproducts can ruin the taste of your food. They also aren’t good for your body (more on this in a second).

An oil’s stability generally depends on its fatty acid composition: 

• Saturated fatty acids (SFAs) are the most stable. Their molecular structure is fully “saturated” with hydrogen atoms, so they resist oxidation, even at high temperatures. Examples of saturated fats are tallow, ghee, butter, MCT oil and coconut oil. 
• Monounsaturated fatty acids (MUFAs) are moderately stable. They have one double bond, which makes them more prone to oxidation than saturated fats but less prone to oxidation than polyunsaturated fats. Examples of monounsaturated fats include olive oil and avocado oil. 
• Polyunsaturated fatty acids (PUFAs) are the least stable. Their multiple double bonds make them highly reactive under heat. Examples of polyunsaturated fats include omega-6 seed and vegetable oils like sunflower, soybean and safflower oils. Omega-3s like the ones found in fish are also polyunsaturated. 

Why Oxidation Matters for Your Biology

When unstable oils oxidize during cooking, the harmful byproducts you ingest don’t just taste bad—they disrupt your cellular biology. Lipid peroxides and aldehydes can damage your DNA and your mitochondria [2] [3]. This slows your metabolism and accelerates aging. Oxidized fats also trigger systemic inflammation, which underlies nearly every chronic disease, from heart disease to neurodegeneration [4].

Olive Oil: The Good, the Bad, and the Polyphenols

Extra virgin olive oil is about 73% monounsaturated fat (mostly oleic acid), ~16% saturated fat, and only ~10% polyunsaturated fat. Compared to seed oils like sunflower or soybean oil, olive oil is far more stable, and it’s packed with polyphenols—natural antioxidants that protect the oil (and your cells) from oxidation [5].

Here’s the catch: polyphenols degrade when exposed to heat. Studies show that at temperatures as low as 100°C (212°F), polyphenols like hydroxytyrosol and oleuropein start to break down. At higher temperatures, they degrade even faster, leaving the oil vulnerable to oxidation [6].

This means that while EVOO can handle light sautéing or baking at lower temperatures (under 350°F) when moisture is present (e.g., cooking with vegetables), it’s not the best choice for most cooking applications including frying, roasting, or grilling

If you’re cooking at high temperatures, you need fats that are built for the heat. This is where animal fats like tallow and ghee shine.

Why Tallow Is Best for Cooking

Tallow (rendered beef fat) is about 50% saturated fat, 42% monounsaturated fat, and only 4% polyunsaturated fat [7]. Its high saturated fat content makes it exceptionally stable under heat. Since saturated fats don’t have double bonds they resist oxidation even at very high temperatures. Tallow has a smoke point of about 430°F (~225°C) [8]. This is when the fat starts to burn. But before reaching its smoke point, tallow’s oxidative stability protects it from breaking down into harmful byproducts.

Tallow also contains fat-soluble vitamins like A, D, E, and K2 (assuming the animal was grass-fed). These nutrients are heat-stable, meaning they don’t break down during cooking.

Why Ghee Is an Ancient Superfat

Ghee (clarified butter) is another high-heat powerhouse. It’s about 62% saturated fat, 29% monounsaturated fat, and 4% polyunsaturated fat, with a smoke point of around 450°F (232°C) [9]. Ghee is free of water and milk solids, which are the parts of butter that burn and oxidize at lower temperatures. Like tallow, ghee contains fat-soluble vitamins. It also contains butyrate, a short-chain fatty acid that supports gut health and reduces inflammation [10]. 

Tallow and ghee are very resistant to oxidation so they’re best for cooking. EVOO resists oxidation at low-to-moderate heat, thanks to its polyphenols—but only up to a point. If you’re cooking, your best bet is to choose tallow or ghee. For salad dressings, drizzling over veggies, or maybe very light sautéing, you can use some olive oil for flavor.  

What Nobody Tells You About Olive Oil 

I recommend about 2-3 tablespoons of olive oil MAX per day for longevity. I know this flies in the face of the “drink olive oil for longevity“ trends. Here is why: 

Your body will benefit from olive oil’s moderate oleic acid (monounsaturated fat) and hydroxytyrosol content (although I take a supplement with 100 times more than you can get in olive oil).

The problem is that excessive intake of oleic acid increases D5D (Delta-5-desaturase) and D6D (Delta-6-desaturase) [11]. These key enzymes control the biosynthesis of long-chain polyunsaturated fatty acids (PUFAs) – the fats we are minimizing!

High D5D and D6D activity can increase your body’s own PUFA production [11]. That means greater oxidative stress – the same type you’d get from just eating omega-6-loaded canola oil.

You can limit D5D and D6D by avoiding excessive olive oil and excessive carbs. That will reduce the availability of long-chain PUFAs, which lowers oxidative stress.

If you eat zero carbs and zero oleic acid, you’ll excessively limit D5D and D6D (just because “less” is good doesn’t mean “none” is better). That could impair essential functions like cell signaling, inflammation regulation, and brain metabolism.

How Biohackers Use Olive Oil  

Olive oil isn’t bad. It’s all about using the right dose and the right type in the right applications. 

My human performance and longevity recommendation is:

1. Don’t eat refined seed oils like canola, corn, soy, safflower, sunflower etc.
2. Eat 2-3 Tbs of high-quality, high-polyphenol EVOO per day – ideally raw to preserve antioxidants
3. Get most of your fats from saturated sources (grass-fed beef fat, butter, ghee, MCT oil, coconut oil)
4. Use grass-fed tallow or ghee for cooking
5. Cook any fat (including tallow and ghee) with oregano, rosemary, and thyme to limit oxidation and for extra antioxidants

Rational and Irrational Takeaways

If you’re cooking at high heat, you’re asking for trouble with olive oil. Sure, the polyphenols will give you some protection, but they’re not bulletproof. EVOO’s limitations mean that tallow and ghee are the clear winners for roasting, frying, and grilling.

Does this mean you should throw out your olive oil? Absolutely not. Use it strategically: drizzle it on your food after cooking, or sauté lightly at lower temperatures with some moisture. That way, you’ll get the benefits of its antioxidants and healthy monounsaturated fats without the oxidative downsides.

You can protect olive oil or even tallow or ghee from oxidation by adding additional polyphenols in the form of rosemary, oregano, and thyme. If you’ve read my longevity book, you already know how important those herbs are for your mitochondria and gut bacteria.

The biohacker in me loves olive oil for its polyphenols and its role in a healthy diet—but the CEO in me knows better than to use the wrong tool for the job. When it comes to high-heat cooking, stick with the fats that won’t betray you: tallow and ghee. When it comes to olive oil, eat it raw and don’t use too much so you don’t excessively increase D5D and D6D. 

Don’t fall for the common mistake we all make with a cognitive bias.

Just because something is good for you (like olive oil) it doesn’t mean that more of it will be better for you.

Your mitochondria will thank you.
