Even though the subject of introverted and extroverted types of personalities is vaguely explored, and while the publications and thesis regarding the subject are often supported with fragile evidence and unconvincing, instinct-based theories, deeper research of this area might give us a broader and in-depth insight on our own nature, as well as the ability to communicate better with the people around us. Throughout a large part of history of mankind introverts were seen as people with weaker personalities which do not possess an adequate social equipment necessary to achieve healthy and long-term relationships. However, in today’s modern, digitalized and subsequently globalized world, their true strength is becoming ever more noticeable. Today we can say with certainty that introverts can achieve strong interpersonal relationships, communicate with others with the same fluency and enthusiasm as their counterparts – extroverts and be exceptional leaders in business aspect, with incredible ability to motivate and inspire others to achieve extraordinary goals. Hence the main goal of this thesis imposes the need to raise awareness about the diversity and a wide spectrum of personalities present in our society but also giving guidance on how to detect and understand the extremely vague and deep character differences with the purpose of alleviating communication barriers and facilitating interpersonal communication as a precursor to executing social endeavors. The importance and key role of introverts in the development of the society as a whole is also the focus of this thesis. We are raising questions regarding the importance that personality traits have on an individual’s private and business success. We pass them through the context of stigmatization present when comparing introverts to extroverts, in which introverts are often being presented as less worthy and less successful. However, through this thesis we will familiarize with the real values and skills an introverted person possesses, what happens in the background of their critical thinking, how they approach challenges they face and through present examples of introverted but extremely successful individuals, show how to achieve great business success in a world seemingly designed for extroverts.
