Here are some things Diana has said over the years, taken from the tribute to her at http://www.camelotintl.com which has wonderful pages on the Royal Family.
ON CHILDHOOD--"I always felt very detached from everyone else. I knew I was going somewhere different."
ON OFFICIAL ENGAGEMENTS--"With Charles at my side, I can't go wrong."
ON MARRIAGE--"I desperately loved my husband and I wanted to share everything together and I thought we were a very good team...Charles and I had our duty to perform and that was paramount."
ON BULIMIA--"I didn't like myself. I was ashamed because I couldn't cope with the pressures...I felt compelled to perform."
ON CHILDREN--"I want to bring them up with security, not to anticipate anything because they will be disappointed...I hug my children to death."
ON BEING A FASHION ICON--"Everyone said I was the Marilyn Monroe of the 1980's and I was adoring every minute of it. Actually, I've never sat down and said "Hooray how wonderful." Never. The day I do we're in trouble."
ON CHARITY WORK--"There are more important things in life than ballet, there are people dying in the streets." "I will run to anyone who calls to me in distress, wherever it is...Nobody can dictate my conduct. I work on instinct. It's my best advisor."
ON THE MEDIA--"I seemed to be on the front page of a newspaper every day, which is an isolating experience, and the higher the media put you...the bigger the drop."
ON SEPARATION FROM CHARLES--"I was the separate wife of the Prince of Wales, I was a problem, fullstop. I'll fight to the end because I believe I have a role to fulfil and I've got two children to bring up."
ON SINGLE LIFE--"People think that at the end of a day, a man is the only answer. Actually, a fulfilling job is better for me...I've got wonderful friends, I've got my boys, I've got my work."
ON AMBITIONS FOR THE FUTURE--"I don't sit here with resentment. I sit here with sadness because a marriage hasn't worked. I sit here with hope because there is a future ahead, a future for my husband, a future for myself, a future for the monarchy."
