It’s rough when you realize that the true saboteur of your dreams is an insider. If you aren’t living up to your highest potential and achieving your goals, blame your brain’s own negativity bias. Positive emotions give us access to the control center in the brain that initiates action toward our goals. Yet, the human brain has evolved to prioritize negative emotions, experiences and memories.

There’s a scientific reason why negative inner voices get more air time in your head than positive ones. Our brains are hard-wired to continuously scan for potential threats. Such focus on the possible worst-case scenario contributed to the survival of our early ancestors. Those who were nervous, tense and attentive to possible danger had a better chance of living to see another day.

As a result, the human brain evolved with a bias towards the negative. Studies show that we recognize and respond more quickly to an angry or sad face, than a happy face. Negative ads and headlines draw more of our attention. Our own shortcomings are far more apparent to us than our achievements. We notice lack more than abundance.
