Doesn't make me feel sad in the slightest bit, she achieved amazing things that she probably (well definitely) would not have had she not been diagnosed with terminal cancer. What she has done is inspirational to all and her family can feel very proud of what she did although I do not doubt that they will miss her terribly, her memory will live on.
I usually don't like to feel emotional about people I don't really know, I particularly hated the Diana circus but Jane does make a difference to my life.
Whenever I'm tempted to over-indulge in self-pity, I think about turning around a 6 month death sentence into 7 years of positive action through sheer determination. Always choose life, always make positive decisions, the alternative is simply a waste.
