If you let the day go - you check in - and you don't write.
If you don't have a plan - you have a collection of tabs open. If you don't have one thing that's more important than anything else, you'll be juggling.
You might eventually get good at juggling, but is that how you want to spend your career?
If you do decide to get good at juggling, over time the metaphor will change. You're no longer juggling in the sense of being out of control; having a list of to-dos all with equal priority - you're actually in complete control of a collection of things. The activities may be similar enough that they lend themselves to being juggled - at least time-blocked.
A set of juggling implements can include soft bean-filled bags of fabric to chainsaws and knives. Essentially, each act of juggling is showing how the person has practiced. You could actually say - hey, look what I've practiced over and over again.
Those who know, do call it practice. You could show up at the circus center and practice. You could be training. You could be getting better. Besides juggling, what else could you get better at? What might you be willing to continue practicing today?
