Thanks to the study of neuroplasticity, scientists are finding that the brain actually grows and changes throughout your life. The intense repitition of a task creates new, stronger neural pathways. As a person becomes an expert in a particular area__ music, sports, public speaking __ the areas of the brain associated with those skills actually grow.

    "We all get better at What we do if we do it repeatedly," according to Dr. Pascale Michelon, adjunct professor at Washington University in St. Louis. Michelon told me about research that has been conducted on everyone from taxi drivers to musicians. Compared to bus drivers, London taxi drivers had a larger hippocampus in the posterior region of the brain. The hippocampus has a specialized role in developing the skill used to navigate routes, whereby the bus driver's hippo-campi was under-stimulated because they frove the same route day after day. Scientists also found that the gray matter involved in playing music (motor regions, anterior superior parietal and inferior temporal areas) was highest in pro amateur musicians, and lowest in non-musicains. Learning a new skill and repeating the skills over and over builds news pathways in the brain.
   Michelon believes these studies also apply to people who speak repeatedly on topics they're passionate about. "The brain areas involved in language __ the areas that help you talk and explain ideas more clearly__ the areas that help you talk and explain ideas more clearly__ these brain areas become more activated and more efficient the more they are used. The more you in public, the more the actual structure of the brain changes. If you speak a lot in public, languages areas of the brain become more developed."
    Compelling communicators, like those  presenters who attract the most views online , are masters in a certain topic because of the inevitable amount of devotion, time, and effort invested in their pursuit, which is primarily fueled by fervent passion.
