Two truths about juggling
1. Throwing is more important than catching. If you're good at throwing, the catching takes care of itself. Emergency response is overrated compared to emergency avoidance.
2. Juggling is about dropping. The entire magic of witnessing a juggler has to do with the risk of something being dropped. If there is no risk of dropping, juggling is actually sort of boring. Perfection is overrated, particularly if it keeps you from trying things that are interesting.
Hence the tricky part--you want to ship in a way that (as much as you can) avoids failure, but when failure comes, moving forward is more effective than panic or blame.
