I learned this back in the early 2000's because I moved to a new city, didn't have a cellphone, and was waiting for my landline and internet to be hooked up. So I literally knew no one and had no contact with the outside world. Then, seriously, I happened to find a set of juggling balls in the back of the closet of the room I was renting—the previous tenant must have forgotten them there. With literally nothing else to do, I taught myself to juggle. Took me longer than an hour, but not all that much longer. (Started with one ball tossing back and forth, then two, before moving to three.)
