Assuming subjects and skills refer to book-learned knowledge rather than life experience: I'm trying to decide what to study in college or through MOOCs like those offered by EdX or Coursera or whether or not I should choose a business or a non-business major. I am trying to decide what to focus on. If I self-studied instead, I wouldn't have any debt from my degree but could still need a degree for other reasons. What specific topics are essential for entrepreneurs to know? For example, there's a lot to learn as a finance major and I'm not sure which topics would be relevant for entrepreneurship. I've tried thinking about it in other ways, for example: "What should a successful entrepreneur/CEO be able to do?" and tried to figure out which subjects will teach me the skills I'll need to achieve those goals.
What first time Entrepreneurs must know is:
1. How Money works. Especially, a good dedicated focus on cash Flow and not Booked Income.
2. Relationship Building. Do not focus on gaining customers, focus more on forging great relationships. Even if it means giving away your knowledge for free. Customers will eventually get attracted to those entrepreneurs who have their best interest and not a selfish motive to generate sales.
