Great people are warranted discussion, but as someone who was once in the academic math world, I had to quit reading after a few sentences. Genius is a very real thing, but I don't need to read adulation after adulation in a series of anecdotes and quotes that will only make me feel inadequate.

Do you think von Neumann's education might have had anything to do with what he was able to achieve?
How about how he was raised by his parents?
Or how about his work ethic, motivation, and attitude towards discovery?
How about the people that he admired and that influenced him?
Learning these things might help us to raise future extraordinary achievers, or might even help us with our own lives/work.
You will not find any of these things in his mathematics, but you might learn about them by studying his life.
