I went to study business management.
Management is a learned set of skills.
It is no different from being a tool and die maker, a surgeon, an auto mechanic, a lawyer, or an engineer. There is a big difference between an aptitude and skills and knowledge. A person has to have an aptitude for a given occupation in order to be successful but but the person must also have the skills and the knowledge. The aptitude may be innate but skill and the knowledge are not. Skill comes from practice and knowledge comes from study.
