An English journalist called Michael Viney told me when I was 25, that I would write well if I cared a lot what I was writing about. That worked. I went home that day and wrote about parents not understanding their children as well as we teachers did, and it was published the very next week.
I never wanted to write. I just wrote letters home from a kibbutz in Israel to reassure my parents that I was still alive and well fed and having a great time. They thought these letters were brilliant and sent them to a newspaper. So I became a writer by accident.
