I don't think the stuff in books helps very much. I mean, for me, I do stuff best if I can see someone else do it and then try it. And I think it's loads better to have someone tell you about while they're showing you than to read some old book while you're sat in the common room. Or, y'know, for me when I am.

Anywiz, have you ever seen someone change? Shame none of us is an animagus or we could show you and tell you about it.
