Juggling Lessons: Distance Matters

I have been thinking for years that I could juggle because I could juggle 3 balls for 5, 6 or some number of tosses.
Then I started trying to juggle for 100 tosses consecutively.

I discovered that I can't juggle. I get to 20, occasionally I get to 30. I lot of days it takes me several tries to get to 20. I realize that to be able to juggle I need to be able to toss and catch and adapt to every toss. Every toss is different. Every catch is different. The shifting and adjusting and handling changes is what makes the ability to juggle.

How this is a model for so many other things in life! We think we can do something because we did it once or a dozen times. But the real measure is can we do it over and over consistently many, many, times.
