In their articles Krakovsky (2007) and Kimball and Smith (2013) revealed that if people believe in what they do and are convinced that they are capable of achieving the result would be more impressive than for those who do not. A person's perception of their personal abilities is directly linked to their learning success. This means that if you believe in yourself, you will work more efficiently and learn faster. The brain mechanism has been shown to be a flexible system that can be improved through different learning approaches. Authors Krakovsky (2007), Kimball and Smith (2013) and Zull (2004) described the human brain as an expandable area. That is to say, intelligence is not restricted. In fact, intelligence is a “neurological process” Zull (2004) that can be improved through training. By practicing, a Krakovsky (2007) “growth-oriented” person (a person willing to put in effort to achieve their goals) will create new connections.
