I don`t think that he is good at maths. It is known mistake when you get some new information and decide that you can change the world. Especially if you are young enough. But the truth is not to run faster to use new knowledge - the right way is to get more information, make some additional research, search other people who tried to do the same. It would help to avoid your own mistakes and problems.
Well to tell the truth, everything has its study and what you say is very real, but he buried himself so much in looking for a way to win that it was impressive how much he failed at everything, in fact if it hadn't been for the support of his family I don't know what could have happened to him, he got the beginning of schizophrenia because he couldn't sleep, after that I think he led a normal life, somewhat more relaxed because I haven't heard anything else since his mother died , but he searched for that in a desperate way with mathematical concepts and simulations through Matlab , he modeled everything there.
