"He was the first person with whom I really discussed my serious ambition to be a writer. Hewas also the only person who thought I was bound to be a success at it, which meant much more tome than I ever told him at the time." Despite many setbacks Rowling persevered in her writing, particularly fantasy stories. But itwasn't until 1990 that she first conceived the idea about Harry Potter. As she recalls, it was on along train journey from London to Manchester that "the idea of Harry Potter simply fell into myhead. To my immense frustration (沮丧), I didn't have a functioning pen with me, and I was tooshy to ask anybody if I could borrow one. I think, now, that this was probably a good thing,because I simply sat and thought, for four(delayed train) hours, and all the details bubbled up inmy brain, and this scrawny, black-haired, bespectacled boy who didn't know he was a wizardbecame more and more real to me." That same year, her mother passed away after a ten-year battle with multiple sclerosis, whichdeeply affected her writing.
