People see a trick we do and think, ‘I wish I could do that … and I’d be willing to train for 10 hours if I could do that.’ But that difference is, we’re will and able to train and practice for 500 hours to pull off one new trick. And that’s how long it takes. We just want it more.  And that’s why we’re able to pull these tricks off.
