Have you ever noticed that we're quick to acknowledge when something bad happens, even if it's something small? Yet, many positive things go on during the day that we never pay attention to.

Did you know there may be a biological reason for this?

Psychiatrist and neuroscientist Paul Maclean postulated the "Triune Brain Theory." He believed the human brain developed in three separate parts. He gave the name "reptilian," or "reptile brain," to the first section. Later research disproved the idea that our brains grew in sections. However, his research continues to have cultural significance.

The reptilian brain (early man's brain) controls the body’s biological functions and our fundamental needs. It acts on impulse. To survive, we had to focus on negative incidents in order to protect ourselves. If a group of people were out picking berries and one of them gets sick, it would be imperative to remember which berries are harmful. Good things could be taken in stride because they can happen over and over and we would still be safe.

In today's world, only recognizing the negative is problematic. It can make us feel anxious and depressed.

Take, for example, a writer who is in the process of trying to publish their novel. They send out their manuscript to 30 publishing houses, and today they received one rejection. The tendency is to remember the one rejection--not the light traffic, the sunny weather, or the money they saved on a sale item. Sure, in this case, the rejection letter may carry more weight, but it will be helpful to balance this negative by taking note of the positives. Dwelling on the rejection would prolong the disappointment.

Challenge yourself to be mindful when something goes your way, even the little things. This new focus should promote positivity and improve one's mental health!
