Every GM will tell you it's an instinct. It's an instinct to be patient, to react, or act, or not to do anything at all. It just comes. What I can say is you must have a plan and a goal and a way to do things. At the end of the day, it's an instinct. Sometimes it's good. Sometimes it's bad.
The truth is that Africa is like everywhere else. There are poor areas, there are rich areas, there is a middle class. Some of those areas are bigger in one country than another, and some countries have real problems that they're working through. But there's great people, good people and a small percentage of bad people - just like everywhere else.
