Attention: Our human brain is built for survival, not thriving. Our ancestors’ main goals were to survive and replicate. Food and water were scarce. And there were many dangers, so they were constantly on the lookout for dangerous animals and rival clans. That’s why our brains developed a negativity bias—if they got caught by surprise by a wolf, they were dead. On the other hand, if they missed an opportunity for food, they still had another chance. So it was more important to focus on the negative rather than the positive.
