If you want to actually get good at juggling, you need to build strong habits, period.
And even better, you need to have a daily routine that you follow most days of the week, if not all days of the week. Personally, what I've found best is to run a short daily routine with balls, clubs, and rings, because that short routine refreshes all the old skills, warms me up, and keeps my foundation really sharp.
And only after I complete that mini daily routine, I add new tricks that I'm excited to learn, which means that I get consistent reps in, I'm able to maintain my skill level, and then on top of that, I'm able to progress on harder stuff while still having fun.
This turns into a cycle, and I'm able to continue to make my daily routine more and more difficult as I run this cycle more and more. It locks in your consistency on "easy" tricks, and it adds on this section that actually drives new skill. So over time, the hard tricks actually just become your regular daily easy routine.
I made a video about this recently so feel free to check it out if you want some motivation :)
