Neil Gaiman's remembrance of Ray Bradbury is very sweet and paints a picture of one of the field's great mensches:
Last week, at dinner, a friend told me that when he was a boy of 11 or 12 he met Ray Bradbury. When Bradbury found out that he wanted to be a writer, he invited him to his office and spent half a day telling him the important stuff: if you want to be a writer, you have to write. Every day. Whether you feel like it or not. That you can't write one book and stop. That it's work, but the best kind of work. My friend grew up to be a writer, the kind who writes and supports himself through writing.
Ray Bradbury was the kind of person who would give half a day to a kid who wanted to be a writer when he grew up.
