How do you feel when you see dull people, people you are smarter than, making money? They are making money because, they are following a simple rule. And what is that rule? Solve a problem, and you will make money. I read about Martins. He was feeding both lecturers and students, and was making money from that, to the point that he made a donation of #200,000 to the school at some point. Mandy was selling sanitary pad in her school, she was nick named sanitary pad. She didn't border because money was coming from it. Let me tell you something, every business is a good business, it depends on how you run it. And yes, there are businesses you can start with zero naira, very possible.
