In my novel, 'First Blood,' Rambo died. In the films, he lives.

When I started 'First Blood,' back in 1968, I was deeply influenced by Geoffrey Household's 'Rogue Male.'

My son died from cancer. My granddaughter died from cancer. I have a lot of reasons to think that reality is not a friendly neighborhood. And the stories that I tell distract me, and if I do the job right, they distract people from things that are happening to them that they wish had never happened.

When I teach writing, I have a mantra: 'Be a first-rate version of yourself, and not a second-rate version of another writer.'

Anybody who sits down to write, and they think 'thriller,' maybe shouldn't be thinking that way. Maybe we should be thinking 'novel,' maybe 'thriller' way in the background, but that these are real people to whom things are happening. It just happens to be a hell of an exciting story.

One of the advantages of having gone to Penn State was having had a scholar for a mentor - Philip Young. Also, a professional writer named Philip Klass taught there. He was a science fiction writer whose pseudonym was William Tenn. As a professional writer, he brought wisdom to teaching because he'd done it for a living.
