How Humans Grew Acorn Brains: Things You Need to Do to Stop Holding Yourself Back

In the face of long-term crises, humanity has often fallen short in its response. When it comes to the climate emergency, our actions have been slow and inadequate. This can be attributed to our Marshmallow Brain, an ancient part of our neuroanatomy that prioritizes instant rewards and immediate gratification. However, alongside this primitive brain, we also possess a more advanced Acorn Brain located in the frontal lobe. This part of our brain, just two million years old, gives us the unique ability to think, plan, and strategize over long timeframes.

To tackle long-term challenges like the ecological crisis, we must tap into our Acorn Brain and become part-time residents of the future. This incredible cognitive ability to think and plan has evolved through various factors. One such factor is "wayfinding," a survival skill developed over two million years. Our ancestors learned to navigate physical space, allowing them to hunt, forage, and find shelter effectively.

Another enabler of long-term thinking is the "grandmother effect." Research has shown that the presence of grandparents, especially maternal grandmothers, reduces infant and child mortality. Older post-reproductive females provide vital childcare, knowledge, and support that increase the survival chances of the young. This creates relationships of trust and reciprocity, where help given in the present is likely to be returned in the future.

Additionally, our capacity for toolmaking played a role in the evolution of our long-term brains. As our brains developed, so did our ability to plan and execute complex sequences of actions. Planning the creation of stone tools paved the way for future-oriented actions such as crop rotation or building monumental structures like pyramids.

While our brains have evolved to think long term, we often hold ourselves back from reaching our full potential. Perfectionism, for example, can be a strong motivator initially but quickly becomes counterproductive. It consumes valuable time, energy, and attention that could be better utilized elsewhere. Instead of aiming for perfection, it's important to recognize that sometimes good enough is sufficient.

In addition, the sunk cost fallacy can hinder progress. If something isn't working despite our best efforts, it may be necessary to let go and walk away. Doubling down on a failing endeavor only prolongs the inevitable. It's crucial to reflect on what initially led us down the current path and be willing to make necessary changes.

Ruminating over past mistakes or worrying about things beyond our control can also hold us back. Instead, we should focus on what we can control and learn from our experiences. By reframing our thoughts and being proactive, we can shift our mindset and move forward.

Thinking of our future selves is another powerful tool for overcoming self-imposed limitations. Our future selves bear the consequences of our present actions, including stress caused by procrastination. By visualizing ourselves in the future, we can make decisions that benefit our long-term well-being.

Creating space for small tasks throughout the day is also essential. Building in short breaks between meetings allows us to address immediate tasks, preventing them from piling up. This reduces the need for last-minute rushes and minimizes context-switching, which can be mentally draining.

Looking forward, rather than dwelling on the past, is crucial for personal growth. When we anchor ourselves to the past, we hinder our ability to embrace the future's possibilities. By focusing on what we can change and setting goals for ourselves, we can foster continuous improvement.

Comparing ourselves to others only diminishes our joy and progress. Each person's journey is unique, and it's important to run our own race. By concentrating on our own growth, overcoming challenges, and setting personal goals, we can find fulfillment and satisfaction.

Finally, embracing the risk of being judged is necessary for personal growth. Stepping outside our comfort zone and contributing our opinions and ideas allows us to be part of the conversation. Starting small and gradually pushing our boundaries can help us build confidence and overcome the fear of judgment.

In conclusion, as humans, we possess the incredible capacity to think and plan for the long term. However, we often hold ourselves back through perfectionism, the sunk cost fallacy, and rumination. By letting go of these limitations and embracing our Acorn Brain, we can tap into our full potential. Taking action, focusing on what we can control, and running our own race are key steps toward personal growth and overcoming long-term challenges.
