It's not a great question and I'll explain what business is then you will understand. Paul Graham famously said that success is selling something people want. Period. A lot of "ideas guys" might have an idea that seems good but straight away, you will need the skills to really prove the concept, to refine it, to pivot if necessary, to take advice lightly, to understand the industry and competitors. Once you start selling, you might need better sales people or no sales people. You might need marketing but you might not. There are two ultimate requirements for success: 1) You do whatever you need to do to make the business succeed (spend in the right places, change, stop doing stuff etc.) and 2) You need to be able to hire a good team that can make this happen. So the reason the question is not good is that you are asking about a specific tool rather than the top-level skills that everyone needs. Caveat: Some people succeed without being great; some people who are great fail. Business is scary, not everyone can do it and being tough and confrontational is a skill that needs to be there to deal with everything else. Good luck!
