Yeah is possible for everyone to be a good businessman, if you really want to be a good business man or woman first you need to learn from those experienced people. If everyone can follow this method of course we all would make a good business. the reason why most people can't make a good business is Because they failed to learn from those experienced people, they're just seeing business in the simplest form not knowing that there are Alot of things that need to be put in place before thier business can work.

Talking about if everyone can turn thier mindset into business minded, well I don't see any possibility in that because there are other Investment out there or side hustle that a guy can chose over business, some people have decided not go into business Because they feel that they don't have business idea, but even when you don't have a business idea if you meet a good mentor there's every tendency that you will become one rather is going to take some time before you can be able to build the knowledge.
