That is true, you spoke admirably, in the world of unlimited knowledge, people's knowledge differs from one another. That is why I say, academic knowledge isn't the one that will bring you the wealth you need. It will enlighten one, show you the pictures how success looks like, and ways to live a better life through adequate knowledge and understanding.
But when it comes to that knowledge to gain wealth and fame, it is inbuilt, sometimes it is naturally gifted. If one doesn't have it, he or she doesn't have it. That's why you see some people rich some poor. You need to ask, why are their still enough poor people in the world today?? Are they not wise enough to become rich?? That is the case of talking about. If one doesn't have that success mark, or favour, let him or her forget about absolute riches.
