It took me about 10 years to get rid of. I'm all right now, though, lovely, I'm throwing some nice darts at the moment, but every now and then I get a bit of a jump. I wish I could find a cure, I'd make a bloody fortune.
During this time I had the singular good fortune of being able to discuss the problem constantly with Einstein. Some experiments done at Einstein's suggestion yielded no decisively new result.
At MIT, I had the good fortune for seven years to teach network theory, which is basic to many disciplines, to one-third of the undergraduate student body. It was an experiment to see how high we could bring their level of understanding, and it exceeded all of my expectations.
Soon after, I returned home to my family, with a determination to bring them as soon as possible to live in Kentucky, which I esteemed a second paradise, at the risk of my life and fortune.
