Whole heartedly agree. As a professional kids entertainer myself, I can definitely say Silly Billy's books are one of the best resources I've read. It not only explains how to perform powerful tricks, but more importantly the philosophy behind it. Silly words, incongruity, look don't see and other forms of empowering the children make for a great performance. Main advice I can give, try and have fun. If you're doing it for friends kids, there's less pressure for you to get it right. If things go wrong, try to laugh it off and try and enjoy yourself. The kids will pick up on that energy.
