I agree that memorising and regurgitating is not useful here, but I do not think the information should come from someone who has built businesses. This is an attempt to teach business school knowledge. Its called "Core MBA"! The best people to provide this information are the people who teach business.

I am very suspicious on insights from people who have been successful at business. Trying to infer from their success is subject to survivorship bias, they may have advantages they are not entirely honest about (especially after the first success), and their experience is usually quite specific.
