We, people, are so very, very complicated that no matter how well drawn a fictional character is, they can't get anywhere near as complex as a real person.
You don't knock television, even if you don't always like what they make of your work. It makes all the difference between being an also-ran writer and very famous.
While most of the things you've worried about have never happened, it's a different story with the things you haven't worried about. They are the ones that happen.
In judging other people's work, particularly short stories, I have noticed how novice writers tell the readers everything about their characters in the first paragraphs, disclose their motives, reveal their recent activities and their future intentions.
Why do we have to have violence, torture, brutality in crime dramas every time we turn on television? Any new crime drama is going to have, sooner or later, a lot of torture and nasty things that make people flinch. Lots of young people I know shrink and flinch from that kind of thing on television, so I think showing it is a mistake.
I don't make any notes, but I do know where to find things. Suppose I need to know where Wexford first talked about his love of the countryside or where he quotes Larkin or what was the beginning of his hatred of racism or where he first encountered domestic violence; I would be able to find it straight away.
People who have had a stroke and are recovering from it love being read to... especially by someone who is a good reader - it does help them to get better.
