The human brain is a network of approximately one hundred billion neurons. Different experiences create different neural connections which bring about different emotions. And depending on which neurons get stimulated, certain connections become stronger and more efficient, while others may become weaker. This is what’s called neuroplasticity. Someone who trains to be a musician will create stronger neural connections that link the two hemispheres of the brain in order to be musically creative. Virtually any sort of talent or skill can be created through training. Rüdiger Gamm, who was a self-admitted ‘hopeless student’, used to fail at basic math and went on to train his abilities and became a famous ‘human calculator’, capable of performing extremely complex mathematics. Rationality and emotional resilience work the same way. These are neural connections that can be strengthened. Whatever you are doing you are doing at any time, you are physically modifying your brain to become better at it. Since this is a foundational mechanism of the brain, being self-aware can greatly enrich our life experience.
