Human nature is pessimistic. It’s been hard-wired in our DNA to help us survive since man began. But we can re-wire our brains to be happy since we no longer need those survival instincts. In the past, we needed to be constantly on the look-out for invaders or predators and aware of our surroundings. It was critical for our survival. And it made us vigilant, critical, negative people out of necessity. But we no longer have to survive like that so those traits and instincts that we have genetically passed down from generation to generation in some form are no longer needed in the same ways. And those genetic tendencies tend to interfere with our ability to be happy – or at least to easily be happy. But there IS good news! We can re-wire the pessimistic, survival genes to be happy genes – sort of.
