Nowadays, individuality is expressed and encouraged at all levels, which ultimately, at the other extreme, inevitably creates ambition. The ambition, which is primarily reflected in the creation of its own rules, procedures, models of action, choice of field of action and a look at synchronization and symbiosis of private and business life, is producing various nonprofit organizations. As a result of this, the question is what ensures a good start, continued development and maintenance of successful nonprofit organization. Given the number of nonprofit organizations that have been run and the nonprofit organizations that still exist, this work is driven by a curiosity for a deeper knowledge of what should a leader own and on what should he insist in his own ambitions related to establishing and running a successful nonprofit organization. Given the specific nature of the nonprofit organization, reflected in the informal position and role of a leader, it is assumed that true leadership comes to the point. In this case, true leadership is assumed to be the one that’s based on one’s own abilities, taking emotional intelligence into account as an important component of successful leadership. Emotional intelligence, which has recently become increasingly important and recognized in terms of its importance and great influence on successful private and business activities, deserves the attention of many. The importance of the topic is reflected in the narrowing the way a leader works with the ultimate goal, which is a successful organization. Today, that lies on a common denominator of speed, promotes overnight success and does not give us a real insight into all that was and it is required to succeed. The theme points to the dependence of the leader and the leadership based on his own acting as a role model and for this reason, it is assumed that the theme can contribute to contemporary organization. The empirical research was conducted through semi-structured interviews with various leaders on a sample of three nonprofit organizations where their similarities and differences were explored. The survey included leaders of nonprofit organizations and their views on the necessary predispositions for successful founding and running a nonprofit organization were analyzed with the aim to provide a clearer insight into what drives and maintains successful nonprofit organizations.
