on chops - rhythm of singles better than doubles.
on backcrosses - rhythm of singles better than doubles. When learning backcrosses, the rhythm is the most important thing to feel for. Also, slow the pattern down as much as possible.
Why I don't want to eat fire? - no skill: just a trick (if you know what to do you can do it)
Four ball shower challengea - 4174 (7441), right arm throws under left, left arm throws under right, leak on left, leak on right
on 5 Balls under the leg - lift leg early to set up for the throw.
on 3 in 1 hand patterns- fountain, reverse fountain, columns, cascade, reverse cascade (easiest). Try to do six throws of each, circulating through all of these patterns. Also, in,in,out (don't forget out,out,in) and in,in,out,out and in,in,in,out,out,out, and in,in,out,out,out and in,in,in,out,out. Of course multiplex 2,1; 804 (try reverse fountain!); multiplex two, grab one. Random! Then there's body throws: behind back, shoulder, under leg, over head, catch behind back, bouncing (w/english, siteswaps, etc.)
on passing - shower gives you twice as much practice as every other. Get good at recoveries so your partner doesn't have to suffer if you drop
on passing 7 clubs - singles easier to control than doubles. Learn with someone that can already do 7 (rather than with a partner who is also trying to learn 7 clubs) - you will learn much faster because you can get away with less than perfect passes but will continue to receive good passes.
on models - the best way to learn is to see people do tricks - so find a juggling club, attend conventions; buy juggling videos.
on friendly competition - it is great to have a juggling partner. You will push each other to higher levels than you can do by yourself and you will both benefit.
on natural talent - I think the average person can learn to juggle and succeed to fairly high levels as long as he has the patience and determination to succeed.
on site swaps - I don't really like to learn from reading numbers that others have calculated, but I enjoy playing around and often some of what feels good turns out to be a site swap and I can use my knowledge of site swaps to learn variations on what I do. Some site swaps I like are the classics: 633, 7333, 645 (and all of it's very fun relatives: 6455, 64555, 645555), 744 (and its relative: 7445 which is like a high 5 ball tennis), 84444, 944444, etc.
Others I like include: 7441 (which I came up with as 4174 while playing with going from fountain to shower and back. This trick, interestingly, is a site swap substitution of 441 for the 333 in 7333),
on competitions - take risks!
