learning without cause

tonight i had an epiphany as i was walking after work. i realized how to backup a wagon with a tractor, this is no small feat for most people. actually most people have serious problems with backing up a cart, but me, for some reason, this popped into my head, i was a farm kid for a long time, and this was one of those skills i just didn't see. i think it is because i have a slightly stubborn streak on occasion. nonetheless tonight i suddently, uncaused, seemed to just realize how it was to be done. has anyone else suddently known such things?
