They say idle hands are the Devil's playthings, well the Devil's a good friend of mine and he's got great hands so put your hands in his hands and you'll have great hands too. NTs, INTPs in particular are known to suffer from overstimulation, this isn't simply the feeling of unease and distress we get in nightclubs it also manifests as that feeling of being bored with everything. You need to reset your stimulation threshold by essentially making yourself as bored as possible, go for a slow walk in a quiet park, sit in a quiet room and just stay there for an hour or two doing absolutely nothing.
Then quickly repeat "the hands make the man" thrice, no more, no less, and put your hands in a mirror.
