Some people say that going from poor to rich is the most difficult thing. Because of the Matthew Effect, the poor get poorer and the rich get richer. Rothschild elaborated on the necessary conditions for success: "It takes great courage and enough prudence to create huge wealth. And to keep this wealth, you need to spend 10 times the wisdom required to create wealth."
