Rick Lavoie is an indespensible resource for anyone dealing with kids. His F.A.T. City Workshop (Frustration Anxiety Tension) DVDs are so insightful and essential to anyone dealing with children that I bought two copies -- one to lend and one to make sure I've always got a copy around.
There's a new DVD and book that he has out about motivation that I wish were available on iTunes.
Please, Mr. Lavoie, get more of your videos and podcasts onto iTunes!
