The speeches were repetitive, but set out in a way that helped me learn something new with each one as I progressed through the book.

That said, and SPOILER - the afterword in which her son that her life isn't as she said and suggests she made it all up is such a, well, a bummer. I feel this should have been mentioned in the introduction rather than doing what Diana absolutely hated - telling everyone it was all a dream at the end of the book.
