A manager means a person who manages a company and directs employees in order to more easily implement processes in management and, ultimately, to achieve the goals of the company. Although the terms manager and leader are often considered the same, this is not the case. Namely, not every leader is a manager nor does every manager have to be a good leader. A leader is a person who has a precisely defined vision and ideas of the company, and the manager puts those ideas into action. Every manager possesses certain qualities, abilities, knowledge and skills, and all this has a great impact on his running the company. The manager should manage the company in such a way as to achieve the required level of productivity and employee satisfaction and to guide and motivate them in their work tasks. Because of his role, the manager invests all his efforts to achieve the common goal of the company. The manager is very important for the success of the company, as well as his personality, which includes his perseverance, strength, hard work, intelligence, tolerance, empathy and much more. These are all characteristics that affect the business (failure) of a company.
