The term "peak performance" or “high performance” refers to performing activities at a maximum level of capacity, requiring willpower, effort, and plenty of training to achieve. However, many may not be able to reach this level, primarily because they are not consciously able to achieve the necessary harmony between the different parts of their brain and body.
The areas of the brain are like different musicians in an orchestra, each playing a role according to their position in the group and creating harmony. The brain operates similarly, and the more balanced and precise the functioning of the different areas, more synchronized is the connection between them, and smoother is the "music" heard.
Unfortunately, our thoughts, emotional states, and environmental stimuli disrupt this harmony, preventing us from reaching a maximum level of performance.
