Well, I think it's the best one yet!
;)
I've read the book Ailsa recommends, it's really very good, a photography friend told me about it.
My favourite on the 'inspiring you and helping you carry on when you feel you're losing' theme, is Art and Fear by David Bayles and Ted Orland...i dip into this all the time...like 'on being a photographer' it's only a few hours read but so worth it.
And love Ailsa's laugh btw :)
