there's nothing to do at all
read a book, take a class, join the gym, take up karate, learn a language on an app, watch youtube videos on how to do ..taichi or some shit, learn a new skill, figure out how to do that math you never learned in school, google the place you'd most like to go and fall down a hole, go to the dog park, go to the regular park, go get a dog!. Put on some clothes, leave your house, get off the fucking internet and do something. Take the bus to a new place in your city and talk to actual people. Have a coffee, get a tea. Watch some people.
Unplug yourself.
