Three balls, 15 minutes

Every day for the past couple of weeks I've been setting my alarm for 15 minutes and practising tossing three balls in the air. I'm getting better. I can keep them going for up to 20 seconds now, but then I always end up throwing one too far in front of me and then the rhythm is broken. More practice time needed. Like, 10,000 more hours of practice. I want to eventually be able to juggle knives on fire while blindfolded.
