Indeed. I taught myself how to juggle recently, because I am fairly clumsy and thought this was something I’d never be able to do, but I wanted to see how far I’d go.

For a month or so, I’d spend 10 minutes a day doing various throwing/catching exercises with 1, then 2, then 3 balls (went on YouTube for resources).

And then at some point - much like you described for playing the blues - all the separate motions all came together and I was juggling.
