MetaGarden(hye-on) – Bestselling Author, Patent Attorney, and Permaculture Farmer
I’m a permaculture farmer and a meta-thinker who has journeyed through computer science, law, and invention to study human growth.
Farming in harmony with nature taught me something profound: just as soil needs a vibrant universe of microorganisms to cultivate nutrient-dense crops, our inner world works the exact same way.
Meta-thinking—the power to trace problems to their roots and pierce through to the core—acts precisely like those rich microorganisms in the mind. Permaculture gifts us this meta-capacity. When it awakens, the commander of our brain, the Prefrontal Cortex (PFC), finally steps into its power. We break free from the anxiety and impulses driven by the limbic system, and at last, reap the fruit of true wisdom.
The Notion system I've built is more than just a productivity tool. It’s a guide designed to awaken the meta-power of your First Brain—the real brain within you, far beyond a mere "second brain."
It’s time to unlock your brain’s true potential. The moment the soil of your thoughts transforms, those once-insurmountable life challenges will gently fall away like light, plantable seeds.
