No two brains are alike, so all brains are different, and they differ from each other, yet each of us has a unique set of circuits and connections that shape our thoughts about things, and make us act in one way. differently from each other as well.
Each person's way of solving a problem is individual, we use our own ways inside our brain, so each human being becomes unique, and individual when it comes to the brain. One of the very limited resources is our working memory, that is, when an idea or even behavior arises.
For you to better understand, basic physical and mental functions use similar circuits, but when it comes to thoughts on more subtle issues, such as purpose and motivation, they involve complex individual sets of circuits, so there is a differentiation from each other.
Literally speaking, our brain does not need to spend so much energy on certain activities, unfortunately something that the brain specializes in doing is always putting us on autopilot, because when it comes to conscious thinking it requires a lot of brain effort.
When we are on autopilot our brain is partially trying to save energy.
