Let me save you the learning curve I went through.
Your body is remarkably good at telling you what it needs — if you know how to listen. Understanding Brain Function is less about following strict rules and more about developing awareness of what works for your unique physiology.
Getting Started the Right Way
Seasonal variation in Brain Function is something most guides ignore entirely. Your energy, motivation, available time, and even cardiovascular fitness conditions change throughout the year. Fighting against these natural rhythms is exhausting and counterproductive.
Instead of trying to maintain the same intensity year-round, plan for phases. Periods of intense focus followed by periods of maintenance is a pattern that shows up in virtually every domain where sustained performance matters. Give yourself permission to cycle through different levels of engagement without guilt.
Before you rush ahead, consider this angle.
Understanding the Fundamentals
One approach to nutrient absorption that I rarely see discussed is the 80/20 principle applied specifically to this domain. About 20 percent of the techniques and strategies will give you 80 percent of your results. The challenge is identifying which 20 percent that is — and it varies depending on your situation.
Here's how I figured it out: I tracked what I was doing for a month and measured the impact of each activity. The results were eye-opening. Several things I was spending significant time on were contributing almost nothing, while a couple of things I was doing occasionally were driving most of my progress.
Common Mistakes to Avoid
One thing that surprised me about Brain Function was how much the basics matter even at advanced levels. I used to think that once you mastered the fundamentals, you could move on to more 'sophisticated' approaches. But the best practitioners I know come back to basics constantly. They just execute them with more precision and understanding.
There's a saying in many disciplines: 'Advanced is just basics done really well.' I've found this to be absolutely true with Brain Function. Before you chase the next trend or technique, make sure your foundation is solid.
The Role of mitochondrial function
The biggest misconception about Brain Function is that you need some kind of natural talent or special advantage to be good at it. That's simply not true. What you need is curiosity, patience, and the willingness to be bad at something before you become good at it.
I was terrible at mitochondrial function when I first started. Genuinely awful. But I kept showing up, kept learning, kept adjusting my approach. Two years later, people started asking ME for advice. Not because I'm particularly gifted, but because I stuck with it when most people quit.
Worth mentioning before we move on:
Building a Feedback Loop
The emotional side of Brain Function rarely gets discussed, but it matters enormously. Frustration, self-doubt, comparison to others, fear of failure — these aren't just obstacles, they're core parts of the experience. Pretending they don't exist doesn't make them go away.
What I've found helpful is normalizing the struggle. Talk to anyone who's good at cortisol levels and they'll tell you about the difficult phases they went through. The difference between them and the people who quit isn't talent — it's how they responded to difficulty. They kept going anyway.
Tools and Resources That Help
I want to challenge a popular assumption about Brain Function: the idea that there's a single 'best' approach. In reality, there are multiple valid approaches, and the best one depends on your specific circumstances, goals, and constraints. What's optimal for a professional will differ from what's optimal for someone doing this as a hobby.
The danger of searching for the 'best' way is that it delays action. You spend weeks comparing options when any reasonable option, pursued with dedication, would have gotten you results by now. Pick something that resonates with your style and commit to it for at least 90 days before evaluating.
Your Next Steps Forward
I recently had a conversation with someone who'd been working on Brain Function for about a year, and they were frustrated because they felt behind. Behind who? Behind an arbitrary timeline they'd set for themselves based on other people's highlight reels on social media.
Comparison is genuinely toxic when it comes to thyroid function. Everyone starts from a different place, has different advantages and constraints, and progresses at different rates. The only comparison that matters is between where you are today and where you were six months ago. If you're moving forward, you're succeeding.
Final Thoughts
Don't let perfect be the enemy of good. Imperfect action beats perfect planning every single time.
