Understanding Fear and Self-Doubt: What Science Says

🔹 According to Harvard neuroscientists, fear is controlled by the amygdala, a part of the brain responsible for detecting threats.

✔ This was useful in ancient times when humans needed to escape predators, but today, the brain treats social risks like career changes or public speaking as life-threatening dangers.

🔹 The Journal of Behavioral Therapy found that self-doubt increases stress and decreases performance by 30%.

The good news? Fear is not reality—it’s just a mental response. And it can be rewired.

Now, let’s break free from this cycle.
