I started juggling after watching a show in my home city in Japan when I was 8-ish. I mostly learned to juggle from books and videos, with much inspiration from Péter Frankl. After moving to California, in middle school I attended juggling festivals and, for about two years, regularly attended Thursday Night Juggling at LA Valley College.
As I haven't practiced very much since 2004, my current juggling skills (excepting my recent advances with 5 clubs) remain the same from that time. I did start a juggling club at my school with one-hour practice once a week to keep up what I already have. I also attended the juggling club at Caltech once in a while, but juggling isn't very popular at Caltech either.
As of fall, 2004, I could juggle 5 balls solid and 6 balls semi-solid. I was struggling with 7 balls, with a record of 35 catches.
My long term goal in juggling has been to juggle 7 balls, 6 rings, and 5 clubs solid. Since I'm starting to work on my 5 clubs again, I think that's the first of these goals that I will be reach. I still have a long way to go with the other props, though. Juggling is so hard!
Like Jason Garfield, I think that juggling shouldn't be dismissed as a mere clown trick. It's actually a really difficult serious activity, having many attributes of a sport. That said, juggling is also fun, and one amusing thing is to juggle different objects. So here's a list:
beanbags, clubs, juggling knives, rings, pencils/pens, erasers, shampoo bottles, scissors, books, coins, chess pieces, chess boards, crystal balls (for contact juggling), scarves, torches (on fire, of course), cards (a couple stuck together), tissue boxes, Rubik's Cubes, 5x5x5's, Skewbs, and other puzzles, apples/bananas/oranges/peaches/apricots/and other tasty fruits, plastic artichalk, soda cans, tennis rackets
